Well, it is certainly a good thing. I can attest to that. I had a job over 10 years ago (my age is showing), where we were given the option of working 5- 8 hr. days, or 4- 10 hr. days. I opted for the 4 - 10 hour days, and then I was able to have a three day weekend (where I then picked up a second part time job those three days). I loved the 4 day work week. At my dads current employer (as a government employee) they also give some employees the option of a 4 day work week.
