4 day workweek is not that common yet (at least not in Denmark). However there are a couple of models for these going over to a 4 day workweek. 1. Same hours/pay typically 36/37 hours a week but longer days 2. Less hours but same pay - employees are able to be just as productive due to being well rested and willing to work more efficiently 3. Less hours /pay - take pay cut and get more free time
