Employer unfair labor practices and union organizing activity: A simultaneous equation model

Abstract

A model is estimated that simultaneously determines the extent of alleged employer unfair labor practices and the outcomes of union organizing activity using biennial, state-level data for 1968–1982. The results suggest that employers are unlikely to use ULPs as a union-avoidance strategy when unions are expected to win representation elections and that the extent of employer ULPs depends on legislative, industrial relations, and workplace characteristics within a state. ULPs also increase the likelihood that workers will choose union representation.
