Through an analysis of solidarity across borders and social groups in connection with and beyond a strike on the part primarily of women workers at a foreign-owned factory in Turkey's Antalya Free Zone, this article contributes to the debate on the two union renewal strategies of transnational labour solidarity and coalition building with social movements. In the case at hand, the extensive strike-related support on the part of external unions and the women's movement illustrates the positive difference that solidarity practices can make. However, looking beyond the strike itself, the case points to significant challenges related to the development of deeper and more proactive solidarity across borders and social groups.
