This study examines gender equality in two Sri Lankan trade unions: the Government Medical Officers Association (GMOA) and the Public Services United Nurses' Union (PSUNU). While women make up a large portion of membership in both unions, they are underrepresented in leadership positions and decision-making. The study aims to understand why women are less active than men in the unions and to identify challenges and opportunities for promoting gender equality. In-depth interviews were conducted with union leaders and members. The findings show that in both unions, women rarely hold leadership roles. Key reasons for lack of women in leadership include women having to balance domestic responsibilities with union activities, and prevailing gender ideologies that discourage women from political involvement.
