Congrats BTW... I know there are many who would love to be in your situation. You could try to disconnect your employer's association with your butt in a chair in the office with the value the get from paying you. One way to do that is to negotiate a remote work arrangement, Tim Ferris or Remote by 37 Signals have some great advice about how to do that. As far as actually setting an expectation that you will work 4 days a week when everyone else works five, unless you've established yourself as a particurally irreplaceable piece of their puzzle.. you're probably going to need to find an employer that embodies that culture, I know there are various companies that do 4 day work weeks. It becomes really difficult for employers to justify why one person isn't around when everyone else is, they're afraid of the dominos... wether justified or not. Again... remote work makes this much easier.
