Abstract: | This paper investigates the gender difference in trade union membership among African men and women in South Africa. Using labour force survey data for 2001 and 2007, we show that at least two thirds of the gender gap is explained by differences in union‐related characteristics. When compared with gender differences in personal, household‐ and job‐related characteristics, disparities in job characteristics account for a larger proportion of the gender gap. These findings imply that women would have had higher unionisation rates than men if they possessed male endowments of union‐related characteristics, especially access to unionised jobs. |
