No serious company is offering this. And none making big money are doing this either.There are already countries that are experimenting with the 4 day work week. Some of them doing 4 ten hour days and some of them even trialing 4 eight hour days. I think a lot more companies should be offering 4 ten hour days. I honestly don't think its hard for them to do. It just needs a cultural change.
Sure, you can work somewhere and make 100k showing up 4x a week
But nobody whose making big bucks has that in their brain housing group.
