delivered the opinion of the Court.
In Allis-Chalmers Corp. v. Lueck, 471 U. S. 202 (1985), this Court held that “when resolution of a state-law claim is substantially dependent upon analysis of the terms of [853]*853an agreement made between the parties in a labor contract,” the plaintiff’s claim is pre-empted by §301 of the Labor Management Relations Act, 1947 (LMRA), 61 Stat. 156, 29 U. S. C. §185. 471 U. S., at 220. The question presented by this case is whether a state-law tort claim that a union has breached its duty of care to provide a union member with a safe workplace is sufficiently independent of the collective-bargaining agreement to withstand the pre-emptive force of §301.

At all times relevant to this case, plaintiff-respondent Sally Hechler was employed by Florida Power and Light Company (Florida Power) as an electrical apprentice. Petitioners, the International Brotherhood of Electrical Workers and its Local 759 (collectively referred to as the Union), are the exclusive bargaining representatives for the bargaining unit in which respondent was employed. On January 11, 1982, Florida Power assigned respondent to a job in an electrical substation that required her to perform tasks she alleges were beyond the scope of her training and experience. Shortly after commencing her new assignment, respondent was injured when she came into contact with highly energized components at the substation.
Two years later, respondent sued the Union in state court in Broward County, Fla. In her complaint, she alleged that “pursuant to contracts and agreements entered into by and between” the Union and Florida Power, and “pursuant to the relationship by and between” the Union and respondent, the Union had a duty to ensure that respondent “was provided safety in her work place and a safe work place,” and to ensure that respondent “would not be required or allowed to take undue risks in the performance of her duties which were not commensurate with her training and experience.” App. 4. The Union, pursuant to 28 U. S. C. § 1441, removed the lawsuit to the United States District Court for the Southern District of Florida on the grounds that the “alleged duty arises [854]*854solely from the alleged collective bargaining agreement between [the Union] and Florida Power,” and therefore that any breach of this duty was actionable under §301. 1 Record 3. Respondent at that time raised no objection to the removal.
In federal court, the Union moved to dismiss the complaint. It argued that respondent’s claim arose solely under federal labor law and was untimely under the applicable federal statute of limitations. Id., at 66-70. Respondent conceded: “The nature and scope of the duty of care owed [her] is determined by reference to the collective bargaining agreement.” Id., at 98. She argued, however, that the basic nature of her action was a state common-law “suit in tort” for the Union’s negligence in failing to provide her á safe workplace. Id., at 100-102. Respondent prayed that the case be remanded to the state court.
The District Court granted the Union’s motion to dismiss. The court observed that the gravamen of the complaint was that the Union had breached a duty of care to respondent to provide her a safe workplace. “Significantly, the duty allegedly owed to [Hechler] flows from the collective bargaining agreement, which imposes a duty on the [Union] to monitor the safety and training of its members.” App. to Pet. for Cert. 3a. The court concluded that because respondent had failed “to demonstrate that the [Union’s] allegedly negligent activity was unrelated to the collective bargaining agreement or beyond the scope of the employee-union fiduciary relationship,” her claim was pre-empted by federal labor law. Id., at 4a. Having found that respondent’s suit was governed by federal law, the court then held that the 6-month statute of limitations adopted in DelCostello v. Teamsters, 462 U. S. 151 (1983), applied to Hechler’s case, and dismissed the suit as untimely.
The Court of Appeals for the Eleventh Circuit reversed. 772 F. 2d 788 (1985). It ruled that the complaint “on its face states a common law negligence claim that may be cognizable [855]*855in state court and is not preempted by the federal labor laws.” Id., at 790-791. The court concluded: “Though the [collective-bargaining] contract may be of use in defining the scope of the duty owed, liability will turn on basic negligence principles as developed by state law.” Id., at 794. Finding that “federal labor law was not invoked in plaintiff’s complaint,” id., at 799, the court directed that the District Court remand the case to the state court for adjudication on the merits.
Because the Eleventh Circuit’s decision appeared to conflict with the decision of the Sixth Circuit in Michigan Mutual Ins. Co. v. Steelworkers, 774 F. 2d 104 (1985), we granted certiorari. 476 U. S. 1113 (1986).

In Allis-Chalmers Corp. v. Lueck, 471 U. S. 202 (1985), we reviewed the pre-emptive scope of §301.1 We think it useful, at the outset, to repeat briefly the background outlined in the opinion in Allis-Chalmers. In Textile Workers v. Lincoln Mills, 353 U. S. 448 (1957), the Court held that § 301 does more than simply confer jurisdiction on federal courts to hear suits charging violations of collective-bargaining agreements. Id., at 450-451. The Court concluded that Congress, through § 301, had authorized federal courts to create a body of federal law for the enforcement of collective-bargaining agreements — law “which the courts must fashion from the policy of our national labor laws. ” Id., at 456. It was explained in Allis-Chalmers, 471 U. S., at [856]*856209, that the Court in Lincoln Mills “understood § 301 as a congressional mandate to the federal courts to fashion a body of federal common law to be used to address disputes arising out of labor contracts.”
Not long after Lincoln Mills was decided, the Court held that state courts have concurrent jurisdiction over §301 claims. Charles Dowd, Box Co. v. Courtney, 368 U. S. 502 (1962). Although the Court in Dowd proceeded upon the hypothesis that state courts would apply federal law when they exercised jurisdiction over §301 claims,2 it was in another case that same Term, Teamsters v. Lucas Flour Co., 369 U. S. 95 (1962), that the Court expressly held that federal law, and not state law, must be used in adjudicating §301 claims.

In Allis-Chalmers Corp. v. Lueck, 471 U. S. 202 (1985), we reviewed the pre-emptive scope of §301.1 We think it useful, at the outset, to repeat briefly the background outlined in the opinion in Allis-Chalmers. In Textile Workers v. Lincoln Mills, 353 U. S. 448 (1957), the Court held that § 301 does more than simply confer jurisdiction on federal courts to hear suits charging violations of collective-bargaining agreements. Id., at 450-451. The Court concluded that Congress, through § 301, had authorized federal courts to create a body of federal law for the enforcement of collective-bargaining agreements — law “which the courts must fashion from the policy of our national labor laws. ” Id., at 456. It was explained in Allis-Chalmers, 471 U. S., at [856]*856209, that the Court in Lincoln Mills “understood § 301 as a congressional mandate to the federal courts to fashion a body of federal common law to be used to address disputes arising out of labor contracts.”
Not long after Lincoln Mills was decided, the Court held that state courts have concurrent jurisdiction over §301 claims. Charles Dowd, Box Co. v. Courtney, 368 U. S. 502 (1962). Although the Court in Dowd proceeded upon the hypothesis that state courts would apply federal law when they exercised jurisdiction over §301 claims,2 it was in another case that same Term, Teamsters v. Lucas Flour Co., 369 U. S. 95 (1962), that the Court expressly held that federal law, and not state law, must be used in adjudicating §301 claims. There the Court observed: “The dimensions of § 301 require the conclusion that substantive principles of federal labor law must be paramount in the area covered by the statute.” 369 U. S., at 103. The need for this uniformity was clearly explained:
“The possibility that individual contract terms might have different meanings under state and federal law would inevitably exert a disruptive influence upon both the negotiation and administration of collective agreements. Because neither party could be certain of the rights which it had obtained or conceded, the process of negotiating an agreement would be made immeasurably more difficult by the necessity of trying to formulate contract provisions in such a way as to contain the same meaning under two or more systems of law which might someday be invoked in enforcing the contract. Once the collective bargain was made, the possibility of conflicting substantive interpretation under competing legal sys-[857]*857terns would tend to stimulate and prolong disputes as to its interpretation.” Id., at 103-104.
The Court thus concluded that “in enacting § 301 Congress intended doctrines of federal labor law uniformly to prevail over inconsistent local rules.” Id., at 104.
While the Court in Lucas Flour observed that federal law was paramount in “the area covered by” §301, 369 U. S., at 103, in Allis-Chalmers the Court defined the range of claims that should be considered as coming within that coverage. The ordinary § 301 case is a contract claim in which a party to the collective-bargaining agreement expressly asserts that a provision of the agreement has been violated. See, e. g., Lucas Flour, 369 U. S., at 104 (claim by employer that strike by union violated provision of collective-bargaining agreement). In Allis-Chalmers, however, the Court considered an employee’s state-law tort action against his employer for bad-faith handling of disability-benefit payments due under a collective-bargaining agreement, and concluded that the interests supporting the uniform interpretation of collective-bargaining agreements under federal common law apply equally in the context of certain state-law tort claims. The Court set forth this basic principle:
“The interests in interpretive uniformity and predictability that require that labor-contract disputes be resolved by reference to federal law also require that the meaning given a contract phrase or term be subject to uniform federal interpretation. Thus, questions relating to what the parties to a labor agreement agreed, and what legal consequences were intended to flow from breaches of that agreement, must be resolved by reference to uniform federal law, whether such questions arise in the context of a suit for breach of contract or in a suit alleging liability in tort. Any other result would elevate form over substance and allow parties to evade the requirements of § 301 by relabeling their contract claims as [858]*858claims for tortious breach of contract.” 471 U. S., at 211.
The Court pointed out that if state law, in the context of a tort action, were allowed to determine the meaning of particular contract phrases or terms in a collective-bargaining agreement, “all the evils addressed in Lucas Flour would recur”; the “parties would be uncertain as to what they were binding themselves to” in a collective-bargaining agreement, and, as a result, “it would be more difficult to reach agreement, and disputes as to the nature of the agreement would proliferate.” Ibid.
In Allis-Chalmers, the Court applied the rule that a tort claim “inextricably intertwined with consideration of the terms of the labor contract” is pre-empted under §301, 471 U. S., at 213, and concluded that the claim in Allis-Chalmers fell within that category. The employee’s allegation there was that his employer and its insurance company intentionally had failed to make required disability payments under a plan negotiated in a collective-bargaining agreement, and that, in so doing, they had breached a state-law insurance duty to act “in good faith” in’paying disability benefits. Id., at 206. The Court observed that any attempt to assess liability on the part of the employer would inevitably involve interpretation of the underlying collective-bargaining contract. First, the disability plan adopted in the collective-bargaining agreement might itself have included an implied requirement of good faith that the employer breached by its conduct. The Court explained: “[I]t is a question of federal contract interpretation whether there was an obligation under this labor contract to provide the payments in a timely manner, and, if so, whether Allis-Chalmers’ conduct breached that implied contract provision. ” Id., at 215. Second, under the relevant state law, the duty of “good faith” on which the plaintiff relied “intrinsically relate[d] to the nature and existence of the contract.” Id., at 216. The concept of “good faith” meant ‘“being faithful to one’s duty or obliga[859]*859tion/” ibid., quoting Hilker v. Western Automobile Ins. Co., 204 Wis. 1, 13, 235 N. W. 413, 414 (1931), and, under state law, that duty was determined primarily by analyzing the responsibilities agreed to by the insurer in the written contract. The Court reasoned: “Because the right asserted not only derives from the contract, but is defined by the contractual obligation of good faith, any attempt to assess liability here inevitably will involve contract interpretation.” 471 U. S., at 218. Inasmuch as federal law must control the uniform meaning given to contract terms in a collective-bargaining agreement, however, an employee’s state-law tort action that necessarily rests on an interpretation of those terms is pre-empted by § 301. Id., at 218-219.3
B
Under the principle set forth in Allis-Chalmers, we must determine if respondent’s claim is sufficiently independent of the collective-bargaining agreement to withstand the preemptive force of § 301. Respondent’s state-law tort claim is based on her allegation that the Union owed a duty of care to provide her with a safe workplace and to monitor her work assignments to ensure that they were commensurate with her skills and experience. Under the common law, however, it is the employer, not a labor union, that owes employees a duty to exercise reasonable care in providing a safe workplace. See, e. g., W. Keeton, D. Dobbs, R. Keeton, & D. Owen, Prosser and Keeton on The Law of Torts 569 (5th ed. [860]*8601984); White v. Consolidated Freight Lines, 192 Wash. 146, 148, 73 P. 2d 358, 359 (1937). Under Florida case law, as under the general common law, the employer “owes a duty to his employees to furnish a reasonably safe place to work, and must use ordinary care and diligence to keep it safe.” 2 Fla. Jur. 2d, Agency and Employment § 154, p. 343 (1977) (footnote omitted); see, e. g., Putnam Lumber Co. v. Berry, 146 Fla. 595, 604-607, 2 So. 2d 133, 137-138 (1941). See also Fla. Stat. §440.56(1) (1981) (“Every employer . . . shall furnish employment which shall be safe for the employees therein, furnish and use safety devices and safeguards . . . and do every other thing reasonably necessary to protect the life, health, and safety of such employees”).
Another party, such as a labor union, of course, may assume a responsibility towards employees by accepting a duty of care through a contractual arrangement. If a party breaches a contractual duty, the settled rule under Florida law is that the aggrieved party may bring either an action for breach of contract or a tort action for the injuries suffered as a result of the contractual breach. See, e. g., Banfield v. Addington, 104 Fla. 661, 669-670, 140 So. 893, 897 (1932); Parrish v. Clark, 107 Fla. 598, 603, 145 So. 848, 850 (1933) (“[A]n action may arise for the breach of the contract, or for the positive tort committed by the violation of a duty arising out of the assumption of the contractual relation”); Safeco Title Ins. Co. v. Reynolds, 452 So. 2d 45, 48 (Fla. App. 1984) (it is a “long-established general principle that injuries caused by the allegedly negligent performance of a contractual duty may be redressed through a tort action”). The threshold inquiry for determining if a cause of action exists is an examination of the contract to ascertain what duties were accepted by each of the parties and the scope of those duties. See 38 Fla. Jur. 2d, Negligence § 17, p. 29 (1982); Vorndran v. Wright, 367 So. 2d 1070 (Fla. App. 1979) (architect’s contract did not include a duty to ensure compliance with safety regulations and thus employee injured on the job had no cause of action [861]*861against the architect); Schauer v. Blair Construction Co., 374 So. 2d 1160, 1161 (Fla. App. 1979) (summary judgment in favor of architect improperly granted when genuine issue of material fact existed regarding architect’s alleged contractual obligation to supervise construction).
In her complaint, respondent alleges precisely this type of tortious breach-of-contract claim. She asserts that “pursuant to contracts and agreements” between the Union and Florida Power, “to which contracts and agreements the Plaintiff was a third-party beneficiary,” the Union owed respondent a duty of care to ensure her a safe working environment. App. 4. Having assumed this duty under the collective-bargaining agreement, the Union — according to the complaint — was then negligent “by allowing [Hechler] to be assigned to work in ... a dangerous location and environment and by failing to provide her with or ascertaining that she had the necessary training, experience, background, and education to work in such a dangerous environment,” and was further negligent in failing to “provid[e] and/or enforc[e] safety rules, regulations and requirements which would preclude such persons with inadequate and insufficient background, training, education, and experience, such as the Plaintiff,. . . from being placed in such an inherently dangerous working environment.” Id., at 5.
Respondent’s allegations of negligence assume significance if — and only if — the Union, in fact, had assumed the duty of care that the complaint alleges the Union breached. The collective-bargaining agreement between the Union and Florida Power, and ancillary agreements between those parties, contain provisions on safety and working requirements for electrical apprentices on which Hechler could try to base an argument that the Union assumed an implied duty of care.4 [862]*862In order to determine the Union’s tort liability, however, a court would have to ascertain, first, whether the collective-bargaining agreement in fact placed an implied duty of care on the Union to ensure that Hechler was provided a safe workplace, and, second, the nature and scope of that duty, that is, whether, and to what extent, the Union’s duty extended to the particular responsibilities alleged by respondent in her complaint. Thus, in this case, as in Allis-Chalmers, it is clear that “questions of contract interpretation . . . underlie any finding of tort liability.” 471 U. S., at 218. The need for federal uniformity in the interpretation of contract terms therefore mandates that here, as in AUis-Chalmers, respondent is precluded from evading the preemptive force of § 301 by casting her claim as a state-law tort action.5
[863]*863l — I HH y — i
If respondent’s suit is treated as a § SOI claim, a court must determine whether her claim is time barred by the applicable [864]*864statute of limitations under federal law. The Union argues that respondent’s claim can be characterized only as a “duty of fair representation” claim against the Union for failing properly to represent Hechler’s interests before the employer, and that her claim must therefore be governed by the 6-month period of limitations prescribed by DelCostello v. Teamsters, 462 U. S. 151 (1983).6 Respondent argues, however, that her suit is not a “duty of fair representation” claim, but is simply a § 301 claim, on the basis of her status as a third-party beneficiary of the collective-bargaining agree[865]*865ment and the Union’s breach of duties assumed under that agreement.7
The Court of Appeals did not review the District Court’s holding that the 6-month period of limitations adopted in DelCostello governs Hechler’s suit, because it concluded that respondent’s claim was not pre-empted under federal labor law. We believe it appropriate for the Court of Appeals to consider, in the first instance, whether the period of limitations adopted in DelCostello is applicable to Hechler’s claim.
The judgment of the Court of Appeals for the Eleventh Circuit therefore is vacated, and the case is remanded to that court for further proceedings consistent with this opinion.
It is so ordered.
