"Using individual-level time-series data covering the period from 1990 to 2011, this article provides an empirical analysis of how the influence of various aspects of class and ideology on union organization have changed over time in the Swedish context. The primary results indicate that although union density and the influence of class-related aspects and ideology are decreasing, particularly among groups with traditionally high levels of organization, the general trend is not valid for all categories of employees. Rather, it appears that where the tradition of being organized is weaker, the influence of class and class identity is particularly strong. No evidence is identified that supports the thesis of class loyalty vanishing among the young."
