%0 Report %A Baert, Stijn %A Omey, Eddy %T Hiring Discrimination against Pro-Union Applicants: The Role of Union Density and Firm Size %D 2014 %8 2014 Sep %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 8516 %U https://www.iza.org/index.php/publications/dp8516 %X We study the causal impact of revealing pro-unionism during the recruitment stage on hiring chances. To this end, we conduct a randomised field experiment in the Belgian labour market. When matched with employer and sector data, the experimentally gathered data enable us to test the heterogeneity of discrimination against pro-union applicants by the union density in the sector and the size of the firm. We find that disclosure of pro-unionism affects hiring chances in a negative way and that – in line with our expectations based on the literature – this negative impact is stronger in highly unionised sectors. %K randomised field experiments %K trade unions %K union density %K hiring discrimination
