I'll share some statistics with you, and we'll see if that answers your question satisfactorily.
We currently observe a higher rate of union coverage for public sector employees. It stands at 76%, compared with 15% in the private sector. In general, public sector employees have higher salaries. As for the stability of the unionization rate, I don't have that data to hand today, but it's something we can study, depending on the reference period, and we can also disaggregate data.
