The changing character of strikes involving permanent striker replacements, 1935–1990

Using NLRB cases reporting hiring of striker replacements, I provide a longitudinal analysis of 165 strikes from 1935–1990. Strikes since 1981 most closely resembled strikes occurring from 1938–1947: They lasted longer and involved more strikers and more replacements than strikes in the 1950s, 1960s, and 1970s. Interestingly, NLRB disposition of employer unfair labor practice charges remained fairly constant throughout the 55 years analyzed and overwhelmingly favored unions. Although my findings are preliminary, they suggest that more empirical analysis of replacement strikes is warranted. I also suggest how some existing strike models can be readily adapted to explain replacement strike phenomena. I thank Stephanie Mason and Brian Dilley for their research assistance and an anonymous referee for insightful suggestions.
