I think there already are examples of the right sorts of things to do. For example, in Switzerland, it is a law that all employees (barring rare special exceptions) are legally entitled to 4 weeks of vacation, at least 2 weeks of which are entitled to be consecutive, per year.

Making this a law is argued as inefficient by some, and that there could be a part of the job market in which employees seek to negotiate different options, and the mandate for fixed vacation time hinders competition.

My interpretation of reality is that this is false. It just leads to the burnout and anti-human need sublimation I wrote about above -- which should not be viewed as though it is a positive reflection of market clearing conditions or some nonsense, especially not when the participants are often young people with no developed perspective yet on the trade-offs needed for their health and huge information asymmetry disadvantages.

Your suggestion of viewing this as an entrepreneurial problem concerns me, because I think that way of viewing the problem is largely what has led to it being as anti-human and severe as it is.
