Card-Check Laws and Public-Sector Union Membership in the States

Abstract

We examine the impact of state card-check legislation on public-sector union membership. Based on an empirical analysis of data from 2000 to 2009, a time during which eight states enacted card-check legislation for public employees, we find significantly higher levels of public-sector union membership for states that passed card-check legislation in years after the laws were enacted relative to states that did not pass such laws. Moreover, average public-sector union membership increased for the states that passed card-check legislation after the laws were passed relative to their precard-check law union-membership levels.
