The case of Spain is particularly interesting as the unions’ main activity, collective bargaining, is a public good. The text, based on research involving a representative survey of members of a regional branch of the “Workers” Commissions” (Comisiones Obreras) trade union, provides empirical evidence that the union presence in the workplace has a significant influence on members’ propensity for activism. By contrast, the alternative hypothesis based on instrumental reasons appears of little relevance in the Spanish industrial relations context.22 p.195877 bytesapplication/pdfapplication/pdfengAquest document està subjecte a una llicència d'ús de Creative Commons, amb la qual es permet copiar, distribuir i comunicar públicament l'obra sempre que se'n citin l'autor original, la universitat i el departament i no se'n faci cap ús comercial ni obra derivada, tal com queda estipulat en la llicència d'úsRelacions laborals - EspanyaSindicats - EspanyaComisiones Obrerasinfo:eu-repo/semantics/workingPaper
