It's quality of life vs quantity of life. Unfortunately our culture favors quantity... Marx stated that religion was the opium of the masses, ironically work is the opium in a capitalist society... cash, crash, burn...

Four day work weeks have benefits and costs that aren't always considered, that should be prior to taking a pay cut. For those of us that have internal or extermal clients that often have immediate needs, it stacks those needs so there is more urgent communication. It's possible and worth a cut for many, but there are certainly consierations prior to taking a cut.

Assuming I'd still be working 40 hours a week (i.e. four 10-hour days), I wouldn't give anything up for a 4-day work week. Sure, you gain an extra free day, but you'll be spending it catching up on all the stuff you won't get done because there's no time to do anything during the week except work, and working 10-hour days (before travel time) is needlessly stressful (I've been through it when my department was short-handed-- it's not fun). I think the 8-8-8 balance we have now is the best way to go.

As a sidenote, The option for 0% should be there, and going by percentage of income rather than a raw dollar amount isn't really the right way to measure it either as the same percentage can mean something signifcantly different from one person to the next depending on how much they actually make.

I don't want to lose any pay. I'd rather just keep working all five days and not give up any money.

My work is highly intense working with middle school students who have severe behavioral difficulties. A four day week would be wonderful for the staff, but it could negatively impact the students. I would consider a 15% decrease in pay to have a four-day.
