I agree. State-enforced Monday-Friday is just bad. In Poland they pretend it's about the employees, while in reality it's the government throwing a bone to the Church. Polish Church is heavily engaged in politics. But to limit employee abuse (rampant in Poland), the working days would have to be fixed in the contract. Plenty of people want to get something done on weekends when they have the most free time, but can't. Someone who is not a catholic would likely have no objections to working on Sunday.
