Faculty unions outside Michigan have reason to be concerned with its passage of legislation barring unions from collecting fees from workers who do not join them. But the experiences of faculty unions in states that adopted such laws years ago suggest that while the measures can be a major hindrance to their work, they are not a death blow. Proponents of such measures, who have succeeded in getting them widely known as "right to work" laws, and even many of the measures' critics see their adoption by Michigan, a stronghold of organized labor, as portending support for them in statehouses elsewhere. Among the states likely to seriously consider such legislation this year are Missouri, New Hampshire, and Pennsylvania. The measures generally hurt unions' ability to recruit members and raise money by creating situations where workers benefit from a union's advocacy and services without joining it as a dues-paying member or otherwise supporting it financially. A look at faculty groups in states that already have such laws shows, however, that collective bargaining can survive. The laws' impact on unions, for the most part, appear less severe than some labor organizers might fear.
