There is a simple solution. Those that want to work from home all week let them. With that comes a 30% pay cut. I know people who would do it in a second. Those that want to come in 2-3 days a 20% pay cut, and those that want to come in all the time no pay cut. I will guarantee you would have employees in all groups and the company would get the same output as before or more. Those with kids would easily save the 30% on daycare, and they would be around for their kids which is a win for all society. The young ones that want to be in the tech world would still be getting paid good at a 30% cut. Just think we all made it during the bad times of the pandemic. Everyone would need to give a little for it to work. Managers and higher would come in all week as well.
I think @ugh+1gtIuRWo is onto something.
