Using data from six union certification election cases (three union wi
ns and three union losses) in the United States, this study examines t
he phenomenon of unionization, drawing upon Wheeler's (1985) theory of
industrial conflict. The comparative case study assessment suggests t
hat a union win is related to employee deprivation, calculation as to
union effectiveness, instrumentality perceptions, and attitudes about
unions. In general, the results are somewhat supportive of the theory
and suggest avenues for future research.
