From an ETUC (European TUC) press release:
“Workers who benefit from collective bargaining enjoy up to two weeks extra paid holiday per year, an analysis of EU data for the ETUC has found as millions prepare to return to work after the summer break.
Ten more days holiday on top of the legal minimum is enjoyed by German and Croatian workers whose working conditions are set through negotiations by trade unions and employers.
Workers with collectively negotiated contracts also benefit from an additional week off in a further seven European countries: Denmark, France, the Netherlands, Czechia, Finland, Italy and the UK.
Across Europe, there’s a collective bargaining holiday bonus of 3 days, with those covered by agreements receiving 24.5 days compared to 21.5 days for all workers.”
