MEMORANDUM OPINION AND ORDER GRANTING IN PART AND DENYING IN PART MOTION TO DISMISS

This matter comes before the Court on defendants’1 Motion to Dismiss, filed July 18, 2025. Doc. 18. Defendants move to dismiss Ms. Blackhorse’s complaint (Doc. 1) for lack of subject matter jurisdiction and for failure to state a claim, and they move to dismiss her amended complaint (Doc. 11), as untimely and futile. Id. at 1. Having reviewed the parties’ submissions and the applicable law, the Court grants in part and denies in part the motion to dismiss for the reasons discussed below. BACKGROUND In Ms. Blackhorse’s initial and amended complaint, Docs. 1, 11, she alleges that she began her employment with the United States Postal Service (“USPS”) in February 2023. Doc. 1 at 3; Doc. 11 at 3. She alleges that her supervisor, Dale West, Jr. (“West”), was a mixed-race

1 Specifically, this motion was brought on behalf of the United States, the United States Postal Service, and employees Susan Yarbro, Dale West, Jr., and Michael King in their official capacities. Doc. 18 at 1 n.1. (non-native, Hispanic) man who engaged in discriminatory misconduct against her because she was of Native American descent and was female. Doc. 1 at 3–4; Doc. 11 at 4. Specifically, she alleges that she “was instructed by Defendant West, her immediate supervisor, to act in violation of USPS policies,” and that when she refused to violate those policies, “she was retaliated against with a total disregard for her rights and feelings.” Doc. 1 at 4; Doc. 11 at 4. She further

alleges that she “was disrespected and unfairly criticized by Defendant West regarding her work performance, medical appointments and requests for leave,” and that this treatment resulted “in intentional infliction of physical and emotional distress upon Ms. Blackhorse.” Doc. 1 at 4; Doc. 11 at 4. She claims that she was not paid in full for her work hours, that Mr. West was disrespectful to Native American customers and to Ms. Blackhorse, and that Mr. West directed post office staff “to participate in the improper return or delayed delivery of mail” in violation of applicable laws or regulations and “threatened personnel action against any employee who did not do as he instructed.” Doc. 1 at 4–5; Doc. 11 at 5. Ms. Blackhorse later “bl[e]w the whistle on” Mr. West “by reporting his misconduct to management,” and she alleges that in response,

Mr. West mistreated her “more often and more severely.” Doc. 1 at 5–6; Doc. 11 at 5–6. She also claims that she “discovered that Defendant West was engaging in” sexual activity in the workplace “by keeping ‘sex toys’ on the USPS premises in the Post Office storage unit,” into which he often locked himself “for extended periods of time during working hours.” Doc. 1 at 6; Doc. 11 at 6. She alleges that on August 30, 2023, she “felt physically threatened by Mr. West and was genuinely concerned for her physical safety following an especially-hostile verbal assault perpetrated on her by him,” and in response she called the Jicarilla Apache Police Department to make a report. Doc. 1 at 7; Doc. 11 at 7. She also filed a formal complaint against Mr. West to his supervisor, Defendant Susan Yarbro. Doc. 1 at 8–9; Doc. 11 at 9. On or about August 31, 2023, she reported her concerns to Defendant Michael King. Doc. 1 at 9; Doc. 11 at 9. She alleges that no actions followed to address this conduct or ensure her safety. Doc. 1 at 9; Doc. 11 at 9. Ms. Blackhorse alleges that she took medical leave in early September 2023 based on stress-related illnesses including migraine headaches and panic attacks. Doc. 1 at 10; Doc. 11 at

10. On September 6, 2023, Mr. West issued Ms. Blackhorse an AWOL (or “absent without leave”) letter despite “her requests for medical leave with supporting documentation.” Doc. 1 at 10; Doc. 11 at 10. It is the Court’s understanding from the complaint that Ms. Blackhorse never returned to work. She alleges that she attempted to resolve the situation through other channels, but after those proved unfruitful, she eventually submitted an Equal Employment Opportunity (“EEO”) complaint on July 1, 2024. Doc. 1 at 12; Doc. 11 at 12. “After Ms. Blackhorse submitted her EEO complaint, and nearly ten months after her last paid working date, she received another AWOL letter from the USPS, dated July 12, 2024[.]” Doc. 1 at 12; Doc. 11 at 12. On September 10, 2024, she received notification that she was to be removed from the Postal

Service no sooner than thirty days from receipt of the letter. Doc. 1 at 12; Doc. 11 at 12. Following these events, Ms. Blackhorse filed her initial complaint alleging 1) gender/race/national origin discrimination and illegal retaliation in violation of Title VII; 2) gender/race/national origin discrimination and illegal retaliation in violation of the New Mexico Human Rights Act, N.M. Stat. Ann. § 28-1-7 et seq.; 3) violations of the Federal Whistleblower Protection Act, 5 U.S.C. § 2303(b)(8); 4) violations of the New Mexico Whistleblower Protection Act, N.M. Stat. Ann. § 10-16C-1 et seq.; 5) violations of USPS policies and the USPS Employee and Labor Relations Manual Sections 666.18 and 666.3; 6) tortious interference with employment contract and intentional/reckless/negligent infliction of physical and emotional distress; 7) breach of the implied covenant of good faith and fair dealing in Plaintiff’s employment contract; 8) tortious interference with employment contract; 9) intentional/reckless/negligent infliction of emotional distress/outrageous misconduct; 10) negligent training and supervision; 11) violations of the Federal Tort Claims Act, 28 U.S.C. § 2679(b)(1); and 12) assault. See Doc. 1 at 13–27. In her amended complaint, Ms. Blackhorse

added a count for civil conspiracy. Doc. 11 at 28. LEGAL STANDARD Federal Rule of Civil Procedure 12(b)(6) governs motions to dismiss. “To survive a motion to dismiss, a complaint must contain sufficient factual matter, accepted as true, to state a claim to relief that is plausible on its face.” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009) (internal quotation marks omitted). The Court “accept[s] the well-pleaded facts alleged as true and view[s] them in the light most favorable to the plaintiff.” Clinton v. Sec. Benefit Life Ins. Co., 63 F.4th 1264, 1275 (10th Cir. 2023). However, the Court is “not bound to accept as true a legal conclusion couched as a factual allegation.” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 555

(2007) (citation omitted). ANALYSIS Defendants move to dismiss each of Ms. Blackhorse’s claims. The Court begins with their arguments against amendment to determine which complaint is the operative one for the purposes of the motion to dismiss. I. Amendment Defendants argue that the amended complaint is both untimely and futile. Doc. 18 at 28. Ms. Blackhorse filed her initial complaint on April 3, 2025. Doc. 1. Federal Rule of Civil Procedure
