A survey of unemployed workers was undertaken to determine these individuals' union membership preference. Standard probit specifications reveal that those unemployed workers more likely to require a union position to return to work include female, minorities, workers with greater experience, and those with higher reservation wages. However, both the duration of unemployment and the perception of widespread unemployment lower the likelihood of such a requirement. These results are consistent with the wage and tenure effects of unions and with the influence of unemployment characteristics on job search.
