In Fleetwood Trailer, 389 U.S. 375, 88 S.Ct. 543, the Supreme Court was required to determine whether the employer violated the Act when it hired six new employees who had not previously worked for the company instead of six former strikers who had applied for reinstatement.
In Marsden, the Second Circuit held that a work stoppage was unprotected because the employees failed to associate the work stoppage with a specific demand related to the conditions of employment.
