How later courts describe this case

  • holding that collective-bargaining agreement “must be read as a whole and in light of the law relating to it when it was made”
  • explaining that this protection does not apply where employer did not commit an unfair labor practice
  • affirming the National Labor Relations Board’s interpretation of a provision in a collective bargaining agreement, applying the same, generally applicable common law contract interpretation construct as did the NLRB
  • finding strong policy against unfair labor practices and the right of employees to select their own bargaining representatives precludes implied waiver of right to strike over unfair labor practices
  • finding strong policy against unfair labor practices and the right of employees to select their own bargaining representatives preeludes implied waiver of right to strike over unfair labor practices
  • upholding the reinstatement of striking workers even when the company had hired replacements
  • affirming imposition of reinstatement and backpay under the Act where an employer failed to reinstate employees who had made an “unconditional” offer to return to work
  • in turn quoting United States v. Heirs of Boisdoré, 8 How. 113, 122 (1849)

Headnotes

  1. Labor & Employment Law — Collective Bargaining A collective-bargaining agreement's general "no-strike" clause does not waive employees' right to strike solely in protest against their employer's unfair labor practices, where the contract as a whole deals only with the economic relationship between the parties and the clause's words do not compellingly express such a waiver. 350 U.S. at 279-284
  2. Labor & Employment Law — National Labor Relations Act Section 13 of the National Labor Relations Act, which provides that nothing in the Act shall be construed to interfere with, impede, or diminish the right to strike, does not preclude reliance upon the Act in interpreting a contractual strike-waiver clause, because the Board looks to the contract itself and its context rather than to the statute to define the kind of strike that is waived. 350 U.S. at 283-284
  3. Labor & Employment Law — National Labor Relations Act The 60-day waiting period prescribed by § 8(d)(4) begins upon the giving of notice of a desire to terminate or modify an existing contract, and its purpose is to relieve the parties during the renegotiation period from the economic pressure of a strike or lockout in relation to the subjects of the negotiations. 350 U.S. at 285-286
  4. Labor & Employment Law — National Labor Relations Act The provision of § 8(d) that any employee who engages in a strike within the 60-day waiting period shall lose his status as an employee applies only to strikes relating to the subjects of the negotiations, and does not apply to strikes designed solely to protest against the employer's unfair labor practices; thus employees who strike within that period solely to protest unfair labor practices do not lose their status as employees. 350 U.S. at 284-286
  5. Labor & Employment Law — National Labor Relations Act Where an employer commits unfair labor practices that violate §§ 7 and 8(a) and protect employees' freedom of concerted action and freedom of choice of representatives, any limitation on the employees' right to strike against such violations must be more explicit and clear than the general loss-of-status language of § 8(d) in order to restrict that right at the very time it may be most needed. 350 U.S. at 287
  6. Labor & Employment Law — National Labor Relations Act The cross-references to §§ 8, 9, and 10 of the Act in the loss-of-status clause of § 8(d) do not expand the scope of § 8(d); they merely make clear that if § 8(d) is violated by employees to whom it applies, those employees lose their status as employees for the purposes of §§ 8, 9, and 10. 350 U.S. at 289
