This qualitative study examines whether, and to what extent, gender equality can be used for trade-union revitalisation purposes. The white-collar unions; Unionen and Fackförbundet ST, are two prominent cases of studying actor’s promotion of gender equality on the Swedish labour market. This study sets out two questions; In what ways do they work with gender issues? Why do they work with gender equality - Is it being used strategically or because they think that it is an important issue? The empirical study is based on twenty interviews with the respective union leadership, elected representatives and officials. The results of the study show that both unions are working on gender equality, because their members consider gender equality to be a priority. As regards the issue of gender equality as a strategy, my study shows that Unionen is working on gender equality as a strategy while Fackförbundet ST do not. Unionen do so that they can recruit a new group, namely young members. Therefore, my study shows that gender equality can be used as a union revitalisation strategy. The study also shows that union revitalisation strategies are contextual in the sense that strategies that work in countries with high female employment rates and high female union coverage, are different from strategies that work in countries with low female employment rates and low female union coverage.
