DAMON J. KEITH, Circuit Judge.
Farley Lee (“Plaintiff’) appeals from the district court’s order for summary judgment in favor of Cleveland Clinic Foundation, et al. (“CCF” or “Defendants”). The district court concluded that Plaintiffs claims of race, national origin, and age discrimination and retaliation under Title VII of the Civil Rights Act of 1964 (“Title VII”) and the Age Discrimination in Employment Act (“ADEA”) lacked any genuine dispute as to material fact and that Defendants were entitled to summary judgment as a matter of law. Plaintiff also appeals the district court’s rulings on a motion to strike and a motion to compel discovery. We AFFIRM the district court’s motion rulings and REVERSE the district court’s summary judgment decision.
I. BACKGROUND
Plaintiff is of Chinese descent and was 61 years old at the time of the events at issue. (Lee Br, at 4, 6) Plaintiff was born in India and immigrated to the United States in 1976 when she was 23 years old. (Id.) Plaintiff worked at CCF for thirty-eight years as a registered nurse (“RN”). (Id.) Plaintiff received many awards for her service, including Nurse of the Year. (Id.)
In 2009, Plaintiff began reporting to supervisor Josalyn Meyer (“Meyer”). (Id. at 7) Meyer generally gave Plaintiff positive reviews for her work performance. (Id.)
However, while employed with CCF, Plaintiff began feeling as though she was being discriminated against because of her age. Plaintiff alleged that during performance reviews in 2013 and 2014, Meyer commented on Plaintiffs long tenure, told her “things have changed” and asked her when she was going to retire. (Lee Dep. I. R. #33-5, 305:23-25; 306-1-25; 307:1-3) On a third occasion, Meyer passed by Plaintiff while she was walking in the skyway of the clinic and inquired as to where Plaintiff was going. Plaintiff informed her that she was going to the gym to “de-stress.” (Id. at 306: 12-21; 346: 19-25) Meyer then replied, “My father was a laborer when he was 15 years old and he doesn’t know when to stop.” (Id.)
In addition to age discrimination, Plaintiff began to feel she was being disertan-[491]*491nated against on the basis of race and national origin. Plaintiff alleges that younger nurses called her an “oldbie” or “old bitch” and referred to rice she ate as “lice.” (Lee Dep. R. #33-4 at 170) She asserts that one nurse stated, “you Chinese people eat anything that crawls and walks” and also stated that Plaintiff does not have “chinky eyes” even though she is Chinese. (Id.) In December 2013, Plaintiff reported the incident to a different supervisor, Debbie Brosovich (“Brosovich”), who responded that she was “overreacting” and being “sensitive.” (Lee Dep. R. #33-5 at 342:14-19)
On April 15, 2014, Meyer called Plaintiff into her office to discuss an incident in which Meyer asserted that Plaintiff had been “pushy or abrasive” with a patient. (Lee Aff. R. #29-11 ¶ 11) At that meeting, Plaintiff complained that she was being discriminated against because of her age and race. (Id.) On April 17, 2014, Plaintiff complained to Brosovich that Meyer discriminated against her because of her age and race. (Id. ¶ 12; Lee Dep. R. #33-4 at 165:8-19; Brosovich Dep. R. # 33-1 at 41:11-25) Brosovich informed Meyer of the complaint before calling Human Resources (“HR”) to inform them of the same. (Bro-sovich Dep. R. #33-1 at 162-63)
On April 30, 2014, Meyer issued Plaintiff her first corrective action and performance improvement plan (“PIP”) for “lack of nursing care and communication” and failure to take “personal accountability” for those actions. (Meyer Dep. R. #33-6 at 236-237; 159:20-22) Meyer testified that a patient’s family orally complained that Plaintiff failed to administer medication to the patient, informed the patient that the mistake was a nursing student’s, and urged the patient’s family not to report the error. (Meyer Dep. R. #23-6 at 157-61) However, there is no record of any patient filing a written complaint against Plaintiff. (Meyer Dep. R. #33-6 at 256:19-25; 257:1-23)
After the issuance of the PIP, Plaintiff filed another complaint in writing with CCF’s Senior HR Director, Jill Prender-gast (“Prendergast”), challenging the PIP and claiming a hostile work environment. (Prendergast Dep. R. #33-9 at 116-117; Lee Ex. 82 R. #29-17 at 2; Lee Ex. 83 R. #29-17 at PagelD #847) Her request for relief under the CCF Right of Review Policy was denied. (Prendergast Dep. R. #33-9 at 89)
On May 12, 2014, Plaintiff met with Lisa Ullman (“Ullman”) from HR and complained that she was being treated differently because of her age and race. (Ullman Dep. R. #33-10 at 58:19-25; 59:1-4; 76:11-21; 81:11-23) Plaintiff told her that Meyer had asked about her retirement and made comments about her own father’s retirement. (Id. at 77:17-25; 78-1-2) Plaintiff told Ullman that she feared her managers were trying to discharge her. (Id. at 100:3-25; 101:1) However, HR did not investigate her complaints because it was determined that “there was nothing to investigate.” (Id. at 105:15-19)
Plaintiff testified that she was given a heavier workload than other nurses. (Lee Dep. R. #33-5 at 307) When she asked for a lighter load, she was admonished. (Id.) Plaintiff testified that assistant nurse managers constantly followed her around the unit and questioned her patients about her work performance, which she claims they did not do to younger, Caucasian nurses. (Lee Dep. R. #33-5 at 309:2-9)
On July 16, 2014, Meyer prepared another corrective action against Plaintiff, which was a written warning, regarding failure to provide safe care for a patient with a serious medical condition. (Lee Ex. 109 R. #29-17 at 4-5) The corrective action alleged that Plaintiff failed to monitor and escalate elevated vital signs to the medical [492]*492team. (Id.) When Plaintiff received the corrective action on Friday, July 18, 2014, she again complained of discrimination and told Meyer that she planned to get a lawyer. (Meyer Dep. R. #33-6 at 243:23-25; 244:1-7) A few hours later, she was suspended for at least three workdays pending investigation for allegedly confronting the patient after receiving the corrective action, telling the patient that she was being fired, and upsetting the patient, who then complained about the incident to the nursing staff. (Brosovich Dep. R. #33-1 at 168:1-16; Defendants’ Ex. 27 R. # 33-21 at PagelD # 3758) Shortly after midnight on July 21, 2014, Plaintiff sent an email to Defendants stating: “Effective immediately on this day of Sunday, July 20, 2014 I am submitting my resignation.... ” (Ex. R. # 32-7 at PagelD # 1052) After Plaintiff resigned, Meyer hired several RNs, all below the age of thirty, starting with Matt Holdyk (“Holdyk”), a twenty-nine year old Caucasian male. (Meyer Dep. R. 33-6 at 291-92)
Plaintiff filed a discrimination complaint in federal district court. (Complaint R. #1) During the pendency of the case, Plaintiff received employment files for each nurse in her unit; she filed a Notice of Discovery Dispute with the court challenging CCF’s faitee to provide employment files for an additional 80 nurses who worked on units different from Plaintiff but who were still under Meyer’s supervision. (Notice R. #14) As an apparent compromise, the district court granted only a random sampling of ten percent of the 80 files. (Order R. #18 at PagelD 227) The district court found that compelling the production of all 80 of the files would be unduly burdensome for Defendants. (Id.)
CCF later filed a Motion for Summary Judgment on the basis that Plaintiffs claim lacked any genuine dispute as to material fact and that Defendants were entitled to judgment as a matter of law. (MSJ R. #23) The Motion included a declaration from Meyer and business records she authenticated. Plaintiff moved for an extension of time to file a response to the Motion. (Motion R. #24) The district court granted the extension and ordered that “there will be no further extensions given the Final Pretrial and Trial dates.” (Order issued 11/10/2015) Plaintiff then sought to extend the page limit by an additional ten pages. (Motion R. #25) The district court granted an extension of five pages. (Order issued 11/13/2015) Plaintiff then filed her brief in opposition of the Motion for Summary Judgment. (Opp’n. R. #29)
Later, Plaintiff filed a Motion to Strike Meyer’s declaration, which was made after Meyer’s deposition testimony. (Motion R. #30) Plaintiff argued that the declaration was inconsistent with prior record evidence and contained or incorporated documents that were inadmissible hearsay, unfairly prejudicial, and not properly authenticated. (Id.) The district court denied the motion, finding that Plaintiff was aware of these arguments at an earlier time, but only made them after filing her opposition to the summary judgment motion to avoid the page limit by asserting the argument in a separate motion. (Order R. #31)
The district court later granted CCF’s Motion for Summary Judgment. (Order R. #34) Plaintiff timely appealed. (Notice R. #36)
II. DISCUSSION
A. Standard of Review
“We review a district court order granting summary judgment de novo.” Coble v. City of White House, Tenn., 634 F.3d 865, 867 (6th Cir. 2011) (citation omitted). “Summary judgment is proper if the evidence, taken in the light-most favorable to [493]*493the nonmoving party, shows that there are no genuine issues of material fact and that the moving party is entitled to a judgment as a matter of law.” Id. at 867-68 (quoting Schreiber v. Moe, 596 F.3d 323, 329 (6th Cir. 2010)).
Because the district court granted summary judgment in favor of Defendants, it is important to impress upon our standard of review in this case.
Summary judgment should be granted only where the moving party is entitled to judgment as a matter of law, where it is quite clear what the truth is and no genuine issue of fact remains for trial. The purpose of the rule is not to cut litigants off from the right to trial by jury if they really have issues to try.
Rogers v. Peabody Coal Co., 342 F.2d 749, 751 (6th Cir. 1965) (citing Sartor v. Arkansas Nat. Gas Corp., 321 U.S. 620, 627, 64 S.Ct. 724, 88 L.Ed. 967 (1944)) (emphasis added).
B. Analysis
1. Age, Race, and National Origin Discrimination Claims
Plaintiff alleges that CCF discriminated against her based on her age, race, and national origin. “Title VII provides that it shall be unlawful for an employer to ‘discharge any individual, or otherwise to discriminate against any individual with respect to ... compensation, terms, conditions, or privileges of employment, because of such individual’s race[ ]’ ” or national origin. Weeks v. Michigan Dept. of Comty. Health, 587 Fed.Appx. 850, 855 (6th Cir. 2014) (quoting 42 U.S.C. § 2000e-2(a)(1)). Further, “[t]he ADEA prohibits employers from discriminating ‘against any individual with respect to his compensation, terms, conditions or privileges of employment, because of such individual’s age.’” Ercegovich v. Goodyear Tire & Rubber Co., 154 F.3d 344, 350 (6th Cir. 1998) (quoting 29 U.S.C. § 623 (a)). “A plaintiff may establish a claim of discrimination either by introducing direct evidence of discrimination or by proving inferential and circumstantial evidence that would support an inference of discrimination.” Weeks, 587 Fed.Appx. at 855 (citation omitted).
Plaintiff alleges that she can prove direct evidence of discrimination. “Direct evidence is evidence that requires the conclusion, without any inference, that unlawful discrimination was at least a motivating factor in an employer’s actions.” Douglas v. Eaton Corp., 577 Fed.Appx. 520, 523 n.1 (6th Cir. 2014) (citing Johnson v. Kroger Co., 319 F.3d 858, 865 (6th Cir. 2003)). “Any discriminatory statements must come from decisionmakers to constitute evidence of discrimination.” Flones v. Beaumont Health System, 567 Fed.Appx. 399, 404 (6th Cir. 2014) (citations omitted). “Statements by nondecisionmakers, or statements by decisionmakers unrelated to the decisional process itself, do not satisfy the plaintiffs burden to demonstrate animus.” Id.
In her opposition to summary judgment, Plaintiff argued that Meyer’s questions to Plaintiff concerning when she would retire constituted direct evidence of age discrimination. (Lee Op. R #29 at 23) Plaintiff also argued that her coworkers’ comments that she was an “oldbie” and their derogatory comments about her Chinese heritage constituted direct evidence of discrimination because her supervisor refused to investigate the allegations after she made the complaint. (Id.) However, the proffered racial comments are not direct evidence of discrimination because a decisionmaker did not make them. They were made by Plaintiffs coworkers. See Flones, 567 Fed.Appx. at 404. Additionally, Meyer’s comments regarding Plaintiffs retirement decisions are not direct evidence of age discrimination [494]*494because they require an inference that Meyer’s comments concerning retirement were a proxy for age discrimination. That is, her comments require us to infer that she asked Plaintiff about her retirement because she wanted to pressure Plaintiff to retire and was motivated to do so on account of Plaintiff’s age. Further, Meyer’s comments regarding retirement were unrelated to the decisionmaking process and accordingly do not provide direct evidence of unlawful discrimination. See id.
Because Plaintiff lacks direct evidence of discrimination, we look for circumstantial evidence, which requires employing the burden-shifting framework set forth in McDonnell Douglas Corp. v. Green, 411 U.S. 792, 93 S.Ct. 1817, 36 L.Ed.2d 668 (1973). See Weeks, 687 Fed.Appx. at 855.
Under McDonnell Douglas, Plaintiff bears the initial burden of establishing a prima facie case of discrimination. If Plaintiff succeeds in making out the elements of a prima facie case, the burden of production shifts to Defendant[s] to articulate some legitimate, nondiscriminatory reason for its actions. If Defendants satisf[y] [their] burden of production, the burden shifts back to Plaintiff to demonstrate that the proffered reason was not the true reason for the adverse action.
Id. (internal citation and quotation marks omitted).
a. Prima Facie Case
To establish a prima facie case of discrimination, Plaintiff must prove that she was: (1) a member of a protected class; (2) subjected to an adverse employment action; (3) otherwise qualified for the position held; and (4) replaced by someone outside of the protected class or that similarly situated employees outside of the protected class were treated more favorably. Clayton v. Meijer, Inc., 281 F.3d 605, 610 (6th Cir. 2002) (citation omitted). It is undisputed by the parties that Plaintiff is a member of a protected class and qualified for the RN position. CCF asserts that Plaintiff did not suffer an adverse employment action because they did not discharge her and thus she cannot prove that similarly situated employees were treated more favorably.
i. Adverse Employment Action
Plaintiff argues that CCF subjected her to various adverse employment actions, including unwarranted discipline, increased surveillance, termination, or in the alternative, an indefinite suspension without pay. (Lee Br. at 26) Plaintiff additionally argues constructive discharge. (Id. at 31)
An adverse employment action is “a materially adverse change in the terms of ... employment.” Kocsis v. Multi-Care Management, Inc., 97 F.3d 876, 885 (6th Cir. 1996). “Termination, decrease in wage or salary, change in title, diminished material responsibilities, or a material loss of benefits are all examples of a materially adverse change.” Mensah v. Michigan Dept. of Corrections, 621 Fed.Appx. 332, 334 (6th Cir. 2015).
1. Increased Surveillance and Discipline
Increased surveillance and discipline, whether warranted or not, do not constitute a material adverse change in the terms of employment in the discrimination context because those actions do not “constitute[] a significant change in employment status, such as hiring, firing, failing to promote, reassignment with significantly different responsibilities, or a decision causing a significant change in benefits.” White v. Baxter Healthcare Corp., 533 F.3d 381, 402 (6th Cir. 2008).
[495]*4952. Termination
Plaintiff argues that the district court erred, in finding that CCF did not terminate her. Plaintiff asserts that CCF terminated her by telling her never to return to her place of work and informing her that they would mail her belongings. (Lee Dep. R. 33-4 PageID #1582) CCF responds by claiming that there is no evidence that it intended to terminate Plaintiff. However, when viewing the evidence in a light most favorable to Plaintiff, a jury could conclude that these actions established that CCF intended to terminate her. Thus, whether CCF terminated Plaintiff is a fact question for a jury to decide and the district court erred in making that finding at the summary judgment stage.
Even if a factfinder could conclude that CCF did not terminate Plaintiff, there is a genuine issue of whether CCF constructively discharged her. “To demonstrate a constructive discharge, the plaintiff must show that (1) the employer deliberately created intolerable working conditions, as perceived by a reasonable person; (2) the employer did so with the intention of forcing the employee to quit; and (3) the employee actually quit.” Hurtt v. International Services, Inc., 627 Fed.Appx. 414, 420 (6th Cir. 2015) (citation omitted). It is undisputed that Plaintiff resigned, satisfying the third prong; consequently, we analyze the first two prongs of constructive discharge.
When analyzing the prong of intolerable working conditions, this court has held that “whether a reasonable person would have felt compelled to resign depends on the facts of each case, but we consider several factors, including but not limited to, reduction in salary and badgering, harassment, or humiliation by the employer calculated to encourage the employee’s resignation.” Id. Drawing all inferences in favor of Plaintiff, the record reflects that CCF employees subjected Plaintiff to humiliation through derogatory racial slurs, and pertinently, that these slurs generally went uninvestigated by'CCF despite Plaintiffs complaints. Further, the record demonstrates that Meyer questioned Plaintiff about her retirement on various occasions, which a jury could conclude was harassment. The district court found that none of these events would amount to evidence of an intolerable working environment. However, in Logan v. Denny’s, Inc., 259 F.3d 558 (6th Cir. 2001), a case with similar facts, we determined that a genuine issue of material fact remained as to whether the plaintiff was subject to intolerable working conditions. In Logan, management and co-workers made comments to an employee such as “We don’t serve ‘grits’ here,” “You’re probably used to that ‘first of the month riish,’” and “These must have been some of your people,” when referring to people who did not want to pay for their food. Id. at 572.1 This court reasoned that the comments carried “an inference of invidious discrimination” in that they were made because of the employee’s race, “sufficient enough to create a question of fact as to whether the comment[s were] harassing and created an intolerable atmosphere.” Id. While this court in Logan acknowledged other adverse employment actions that were enough to satisfy the constructive discharge inquiry, including demotion and salary and responsibility reduction, it went on to analyze the racially motivated comments in isolation and concluded that they were enough to create a fact question of whether the plaintiff was subject to an intolerable work environment. Id. Similarly, in this ease, the comments made to Plaintiff [496]*496by her coworker, on their own, carried an inference of invidious discrimination as they were even more explicit than those made in Logan. They were overt comments that clearly concern Plaintiffs race and national origin. While management did not make those comments, viewing the evidence in a light most favorable to Plaintiff requires the finding that management failed to investigate the comments when Plaintiff informed them of such, thus unreasonably failing to respond to the coworker harassment. Cf. Hawkins v. Anheuser-Busch, Inc., 517 F.3d 321, 341 (6th Cir. 2008) (concluding that summary judgment was improper when the evidence showed that employer failed to investigate harassment complaints). Further, the record shows that Meyer questioned Plaintiff regarding her retirement on several occasions. Unlike our case of Lindsey v. Whirlpool Corp., 295 Fed.Appx. 758, 770-71 (6th Cir. 2008), where the plaintiff was subjected to similarly discriminatory comments but her employer promptly investigated and addressed the comments, CCF generally failed to investigate Plaintiffs complaints. Accordingly, a genuine issue of material fact remains as to whether these comments constituted harassment and humiliation strong enough to compel resignation and whether any failure to! investigate contributed to a constructive discharge.
With regard to the second prong of constructive discharge, the employer’s intention to force the employee to quit, a reasonable juror could find that Meyer intended to question Plaintiff repeatedly about her retirement plans because she was an older employee who may be more likely to retire and that she did so with the intention that Plaintiff quit her job. A reasonable juror could further find that CCF intended not to investigate Plaintiffs claims of age, race, and national origin discrimination because it wanted Plaintiff to leave her job, Those findings will hinge upon credibility determinations. “Credibility determinations, the weighing of the evidence, and the drawing of legitimate inferences from the facts are jury functions, not those of a judge, whether [s]he is ruling on a motion for summary judgment or for a directed verdict.” Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 255, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). Thus, factual questions remain for a reasonable jury to answer with regard to constructive discharge and Plaintiff has established this element of her prima facie case.
3. Indefinite Suspensión Without Pay
In White v. Burlington Northern, this court held that suspension without pay constitutes an adverse employment action. White v. Burlington Northern & Santa Fe R. Co., 364 F.3d 789, 803 (6th Cir. 2004). The record reflects that Meyer suspended Plaintiff on Friday, July 18, 2014, for at least three days. (Defendants Exhibit 27 R. # 33-21 at PagelD # 3758) Meyer instructed Plaintiff not to return to work or call into the unit until she was instructed to do so. (Id.) While Meyer testified at her deposition that she suspended Plaintiff with pay, (Meyer Dep. R. # 33-6 at 263-64), Brosovich testified that Plaintiffs suspension was without pay. (Brosovich Dep. R. # 33-1 at 188) Plaintiff stated that she has not received payment for the days that she was suspended. (Lee Aff. R. #29-11 at PagelD # 720) The district court found that whether Plaintiff was suspended with or without pay was not dispositive because Plaintiff submitted her resignation on Monday, July 21, 2014, at 12:08 a.m., before her suspension could take effect. (Ex. R. # 32-7 at PagelD # 1052) The district court reasoned that the suspension was not an adverse employment action because Plaintiff resigned before she could suffer' [497]*497any financial loss as a result of the suspension. (Order, R. #34 at 16)
While we have not directly dealt with the issue of whether a suspension without pay must be served, or simply issued, to constitute an adverse employment action, our sister circuits have persuasively held that service of a suspension is a requirement if it is to rise to the level of an adverse employment action. The Seventh Circuit has held that “a suspension without pay that is never served does not constitute an adverse employment action.” Nagle v. Village of Calumet Park, 554 F.3d 1106, 1120 (7th Cir. 2009) (internal quotations and citations omitted). This interpretation is in keeping with the Supreme Court’s observation that discrimination must involve a “tangible” employment action that "in most cases inflicts direct economic harm.” Burlington Industries, Inc. v. Ellerth, 524 U.S. 742, 762, 118 S.Ct. 2257, 141 L.Ed.2d 633 (1998). Failure to allow that harm to manifest prevents the tangible employment action from taking place. We have cautioned employees “not to assume the worst, and not to jump to conclusions too fast.” Agnew v. BASF Corp., 286 F.3d 307, 310 (6th Cir. 2002) (quoting Garner v. Wal-Mart Stores, Inc., 807 F.2d 1536, 1539 (11th Cir. 1987)). Thus, consistent with the Supreme Court, the holdings of our sister circuits, and this court’s own pronouncements, Plaintiffs suspension without pay was not an adverse employment action because she resigned before she could serve the suspension.
ii. Replacement and Treatment of Similarly Situated Employees
To prove the last prong of the prima facie case, Plaintiff asserts that Meyer hired a 29-year-old Caucasian male, Hol-dyk, to replace her. The district court found that “it was not clear from the testimony that the male was actually hired to replace [Plaintiffs] position or merely was selected for a job [Plaintiff] had previously performed.” (Order, R. #34 at 18) Meyer testified that Holdyk was among a group of individuals who applied for nurse positions that were open before Plaintiffs resignation, but Holdyk was the first hired following Plaintiffs resignation. Whether CCF hired Holdyk to replace Plaintiff is a genuine issue of material fact for the jury to determine. Viewing the evidence in the light most favorable to the nonmoving party, however, would require the district court to find that Meyer hired Holdyk to replace Plaintiff. Consequently, Plaintiff establishes the final element of her prima facie case and the district court erred in finding that Plaintiff failed to prove a pri-ma facie case of discrimination at the summary judgment stage.2
[498]*498b. Legitimate, Non-Discriminatory Reason and Pretext
After Plaintiff proves her prima facie case, the burden shifts to CCF to articulate a legitimate, nondiscriminatory reason for its actions. Once the legitimate nondiscriminatory reason is established, Plaintiff must show that the reason proffered by CCF is merely a pretext for discrimination. “A plaintiff can demonstrate pretext by showing that the proffered reason (1) has no basis in fact, (2) did not actually motivate the defendant’s challenged conduct, or (3) was insufficient to warrant the challenged conduct.” Maben v. Southwestern Med. Clinic, 630 Fed.Appx. 438, 443 (6th Cir. 2015) (quoting Dews v. A.B. Dick Co., 231 F.3d 1016, 1021 (6th Cir. 2000)).
Plaintiff argues that neither patients nor their family members filed a grievance or complaint against her in 2013 or 2014, and that the only written evidence of complaints are notes made by Meyer in Plaintiffs employee file that state that certain patients or family members complained. CCF asserts that it suspended Plaintiff because of an inappropriate interaction with a patient on July 18, 2014. However, while Plaintiff admitted that the interaction with the patient happened, she disputes Defendants’ characterization of the incident as her improperly confronting the patient. Plaintiffs version involves the patient asking her whether Plaintiff was in trouble with CCF following the failure to monitor her vital signs, to which Plaintiff answered in the affirmative. (Lee Dep. R. #33-5 at 265) Plaintiff testified that, “the July 18 incident is just turned around and fabricated.” (Id. at 268-69) Therefore, because of the divergent accounts, a factual question remains concerning whether the reason for her suspension was pretextual despite her admissions.
Additionally, a jury must still consider issues concerning Meyer’s comments to Plaintiff regarding retirement, HR’s failure to investigate any claims of discrimination, the fact that Meyer suspended Plaintiff, Plaintiffs replacement by Someone outside of her protected class, and that similarly situated employees were not suspended for possibly similar conduct in order to make appropriate credibility determinations. Further, the evidence shows that although Plaintiff was suspended for a specific patient complaint after many alleged patient complaints, there were no written complaints against Plaintiff in the record. Thus, a question remains as to whether there was any basis in fact for the actions that led to the suspension and whether Defendants were motivated to constructively discharge Plaintiff based upon race, national origin, or age discrimination and not because of any misconduct committed by Plaintiff. Thus, it was improper for the district court to grant summary judgment in favor of Defendants.3
[499]*4992. Retaliation
“The McDonnell Douglas burden-shifting framework also applies to retaliation claims.” Martin v. Toledo Cardiology Consultants, Inc., 548 F.3d 405, 412 (6th Cir. 2008) (citing Clay v. United Parcel Serv., Inc., 501 F.3d 695, 713 (6th Cir. 2007)).
To make out a prima facie case of retaliation, a plaintiff must establish that: (1) she engaged in activity protected by Title VII; (2) this exercise of protected rights was known to the defendant;. (3) the defendant thereafter took an adverse employment action against the plaintiff; and (4) there was a causal connection between the protected activity and the adverse employment action. .
Id. (citing Ford v. Gen. Motors Corp., 305 F.3d 545, 552-53 (6th Cir. 2002)). “Once the plaintiff has made out a prima facie case, the burden of production shifts to the employer to proffer a legitimate, nondiscriminatory reason for its actions.” Id. (citing Niswander v. Cincinnati Ins. Co., 529 F.3d 714, 720 (6th Cir. 2008)). “If the employer meets this burden, the burden then shifts to the plaintiff to demonstrate by a preponderance of the evidence that the legitimate reason given by the employer was a pretext for retaliation.” Id.
The district court assumed that Plaintiff engaged in a protected activity, which the defendants were aware of, but found that there was no adverse employment action. This court has held that the “burden of establishing a materially adverse employment action is ‘less onerous in the retaliation context than in the anti-discrimination context.’ ” Laster v. City of Kalamazoo, 746 F.3d 714, 731 (6th Cir. 2014) (quoting Michael v. Caterpillar Fin. Servs. Corp., 496 F.3d 584, 595-96 (6th Cir. 2007)). “A materially adverse employment action in the retaliation context consists of any action that ‘well might have dissuaded a reasonable worker from making or supporting a charge of discrimination.’ ” Michael, 496 F.3d at 596 (quoting Burlington Northern and Santa Fe Ry. Co. v. White, 548 U.S. 53, 60, 126 S.Ct. 2405, 165 L.Ed.2d 345 (2006)).
The evidence shows that CCF subjected Plaintiff to increased surveillance after making a complaint of discrimination and that she was suspended without pay and told not to return until she was called. A reasonable jury could find that these actions would have dissuaded a reasonable worker from making or supporting a charge of discrimination.
The district court did not address the causal connection element of Plaintiffs pri-ma facie case of retaliation. However, a reasonable jury could find that Plaintiff established a causal connection between her complaints of discrimination and expressed intention to hire a lawyer and the adverse employment action. “To establish a causal connection, a plaintiff must proffer evidence sufficient to raise the inference that her protected activity was the likely reason for the adverse action.” Id. (quoting Dixon v. Gonzales, 481 F.3d 324, 333 (6th Cir. 2007)). Further, “in some cases temporal proximity may be sufficient to establish causation.” Hamilton v. Gen. Elec. Co., 556 F.3d 428, 435 (6th Cir. 2009) (citing Mickey v. Zeidler Tool & Die Co., 516 F.3d 516, 523-26 (6th Cir. 2008)). “In Mickey, we held that where an adverse employment action occurs very close in time after an employer learns of protected activity, such temporal proximity between the events 'is significant enough to constitute evidence of a causal connection for the purposes of satisfying a prima facie case of retaliation.” Id. (internal alteration and citation omitted).
[500]*500The evidence, viewed in the light most favorable to Plaintiff, establishes that on April 15, 2014, Plaintiff complained of discrimination. This of course was not her only complaint of discrimination, as her complaints began in 2013 and consistently went uninvestigated. Nonetheless, on April 30, 2014, she was issued a corrective action and PIP. Defendants argue that the decision to issue the corrective action and PIP was made prior to Plaintiffs discrimination complaint and that no matter what protected activity Plaintiff engaged in, Defendants would have still taken the corrective action. However, that is a fact question for a jury to decide. Further, in Hamilton, this court held that increased surveillance after a discrimination complaint is sufficient to establish the causal connection element of a prima facie case of retaliation. Hamilton, 556 F.3d at 436-37. A reasonable jury could find that the close proximity of the adverse employment action to Plaintiffs discrimination complaints and the uncontroverted allegations of increased surveillance are significant enough to show a prima facie case of retaliation. Therefore, summary judgment was inappropriate.
A reasonable jury could find that despite Plaintiffs admissions to certain misconduct, Defendants nonetheless retaliated against her, at least in some part, because' she complained of discrimination. Furthermore, other similarly situated employees who CCF disciplined for similar alleged conduct were not suspended. While the dissent places great weight on CCF’s reasons for suspending Plaintiff, our standard of review requires viewing the evidence in a light most favorable to Plaintiff, and only allows the factfinder to make credibility determinations. As the Supreme Court has stated:
There are many things sometimes in the conduct of a witness upon the stand, and sometimes in the mode in which his answers are drawn from him through the questioning of counsel, by which a jury are to be guided in determining the weight and credibility of his testimony. That part of every case, such as the one at bar, belongs to the jury, who are presumed to be fitted for it by their natural intelligence and their practical knowledge ... and, so long as we have jury trials, they should not be disturbed in their possession of it....
Sartor v. Ark. Nat. Gas Corp., 321 U.S. 620, 628, 64 S.Ct. 724, 88 L.Ed. 967 (1944) (quoting Aetna Life Ins. Co. v. Ward, 140 U.S. 76, 88, 11 S.Ct. 720, 35 L.Ed. 371 (1891)). Thus, it is for a jury to decide whether CCF’s reasons were not only honest, but also whether the proffered reasons were really the impetus for the decision to suspend Plaintiff. Therefore, it was improper for the district court to grant summary judgment in favor of Defendants.
3. Aiding and Abetting and State Tort Claims
The district court found that because Plaintiffs discrimination and retaliation claims lacked merit, her claims of negligent retention, supervision, and hiring, intentional infliction of emotional distress, and aiding and abetting also fail. However, because the district court erroneously granted summary judgment in favor of Defendants, we likewise reverse the judgment on Plaintiffs aiding and abetting and state law tort claims.
4. Denial of Motion to Strike and Motion to Compel
a. Motion to Strike
“We review the decision to grant or deny a motion to strike for an abuse of discretion, and decisions that are reasonable, that is, not arbitrary, will not be overturned.” Seay v. Tennessee Valley Authority, 339 F.3d 454, 480 (6th Cir. 2003). [501]*501Meyer filed a declaration explaining business records that were kept in the regular course of business and were maintained in Plaintiffs employee file. Plaintiff asserted that CCF improperly filed Meyer’s declaration after her deposition testimony because the declaration contained facts contrary to her deposition testimony. See Reid v. Sears, Roebuck and Co., 790 F.2d 453, 460 (6th Cir. 1986) (“A party may not create a factual issue by filing an affidavit, after a motion for summary judgment has been made, which contradicts her earlier deposition testimony.”) However, Plaintiff had the opportunity to address the issue of Meyer’s declaration, which came after Meyer’s deposition testimony, in her opposition to Defendants’ motion for summary judgment. Plaintiff chose not to address the issue until two weeks after filing her opposition. The district court found that even if it considered the motion, it would not be fully briefed until after the final pretrial and trial dates, to which it already ordered there would be no more extensions. This court has held that “[t]he timing of trials and docket control are matters best left to the discretion of the trial court.” Anthony v. BTR Automotive Sealing Systems, Inc., 339 F.3d 506, 517 (6th Cir. 2003). The district court’s refusal to grant the motion to strike was an exercise in maintaining control of its docket and was not an abuse of discretion, especially when Plaintiff could have moved to strike the declaration at an earlier time. Further, Meyer’s declaration is not substantially different from her deposition testimony, where she asserts that Plaintiff had an inappropriate encounter with a patient.
Plaintiff also argues that Meyer could not have authenticated the business records because'she was not personally aware of the incidents surrounding them. However, in Peak v. Kubota Tractor Corp., this court stated that a custodian of records “must simply be familiar with the company’s recordkeeping practices.” Peak v. Kubota Tractor Corp., 559 Fed.Appx. 517, 522 (6th Cir. 2014) (citing United States v. Weinstock, 153 F.3d 272, 276 (6th Cir. 1998)). Thereafter, “the proper approach is to admit the evidence and permit the jury to detennine the weight to be given the records.” Id. at 523 (quoting United States v. Hathaway, 798 F.2d 902, 907 (6th Cir. 1986)). Thus, the district court did not abuse its discretion when it admitted the evidence and denied Plaintiffs motion to strike.
b. Motion to Compel
Lastly, Plaintiff argues that the district court’s partial denial of her motion to compel prejudiced her in establishing her discrimination claim and allowed the district court to find that she had not proven a prima facie case of discrimination. “We review a district court’s discovery-related rulings under the highly deferential abuse-of-discretion standard.” Loyd v. Saint Joseph Mercy Oakland, 766 F.3d 580, 588 (6th Cir. 2014). This court “will intervene only if it was an abuse of discretion resulting in substantial prejudice.” Surles ex rel. Johnson v. Greyhound Lines, Inc., 474 F.3d 288, 304 (6th Cir. 2007) (internal citation omitted). As we have held, “district courts have discretion to limit the scope of discovery where the information sought is overly broad or would prove unduly burdensome to produce.” Id. (citing Fed. R. Civ. P. 26 (b)(2)).
The district court found that production of comparator employee files for all nurses in all three Meyer-supervised units would be unduly burdensome for Defendants but nonetheless granted a random sampling of ten percent of the 80 comparator files Plaintiff sought. This was in addition to her receipt of comparator files for each nurse in her own unit. Plaintiff does not argue that the district court’s finding that [502]*502production would be unduly burdensome was erroneous, but instead argues that the district court prejudiced her case by denying access to comparator evidence and simultaneously ruling that she lacked evidence of discrimination. Plaintiff has not established substantial prejudice in the denial of the motion.
III. CONCLUSION
For the foregoing reasons, we REVERSE the district court’s summary judgment decision, AFFIRM the district court’s motion rulings, and REMAND for further proceedings consistent with this opinion.
