The world doesn't operate on a 4-day schedule.
Too many are held hostage to a job they don't like because of the benefits.
If we had a system where employees could get their own health insurance at a
decent cost regardless of their employer, you'd see people shift into a
situation where they were happier and the net result would be better for the
employer, too, because he'd have employees that wanted to be there.
That's especially true when a spouse's situation dictates the family
employer situation because of benefits. (The best I've ever seen are
public school teachers who pay $100 a month for family coverage....try buying
that as an individual policy on the open market.)
Try a 4-day, 9-hour work schedule and see if your people are happier working for
you, even if the pay isn't quite as much. Even better if you can get your
system to be more productive than the competition simply because you retain more
expertise than the competition because of this work schedule.
These results parallel other studies I've read and make sense. An issue I see is how employers focus so much on their customers that they
forget about their employees and often employees feel dejected and forgotten.
Employers will say we need to work harder and do this for customers, but
employees see no benefit for themselves -- and this can create dissatisfaction
and turn over.
