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.
Finding that the employer “made a conscious decision to tell the Union nothing about the hiring of permanent replacements, and took active measures to keep the replacement campaign a secret while hiring as many permanent replacements as it could before the Union caught on,” and noting that the employer described the plan as a “well-executed surprise event” that had “[the Union] in a real bind,” and informed a temp agency that “its plans regarding permanent replacements were to be kept ‘hush-hush’ ”
