Do men and women legislators have equal opportunities to carry out their parliamentary duties? An important first step to uncover the parliament's inner life is to evaluate MPs' experiences of their work environment. In this article, we explore the Swedish parliament where women have held over 40 percent of the seats for two decades to test the persistence of gendered norms and practices. Using an originally-collected survey dataset of 279 Swedish MPs (82 percent response rate), we find that women MPs experience greater pressure, higher levels of anxiety, and are subject to more negative treatment than men MPs. Yet, while men and women report participating in the debate and influencing their political party's agenda to the same degree, we conclude that the Parliament's working environment remains gendered in that women pay a higher personal cost for their political engagement.
