Starting from the early 1930s, structural changes in the Bulgarian tobacco industry, prompted by the advent of the world economic crisis and German economic expansionism into Southeastern Europe, led to a deep restructuring of the labor processes, known in the terminology of the time as rationalization, in the Bulgarian tobacco industry. The introduction of the tonga rationalization technology had a deskilling and deeply gendered effect on the industry, making a significant number of skilled male workers redundant, disproportionately decreasing average male wages and leading, in turn, to a further feminization of an already majority-female workforce.

The introduction of the new system provoked a strong response from the organized labor movement, which used a variety of tactics to fight against the new technology: from strikes to petitions to tripartite negotiations. Organized labor's reaction was deeply gendered, an aspect that only becomes truly visible if, in addition to gender and skill, we employ the analytical lens of scale. By following trade union policies on the local, national, and international levels, the article goes beyond the carefully crafted gender-neutral language in official documents to reveal tensions between the conservative attitudes of rank-and-file activists and the official trade union agenda. This is especially evident in communist labor politics, where Bulgarian trade union policies on the local and national levels provoked an intervention on the part of the Profintern between 1930 and 1931. The movement's internal contradictions resulted in a polyvalent, ambiguous, and non-linear trade union policy formed through the clash of and negotiations between local activists’ conservative notions of gendered work and family roles and the radical gender program of international communism.
