what's a job that has a 4-day schedule?

The 2 we use are decent. We've had one or 2 company drivers quit us, work for the DLC as "temps" for us on this account. They are paid less per hour, DLC takes a dollar or two per hour, but they get control over their schedule since they are dispatched one week at a time. "OK, next week can you work Mon-Fri? No, I can work Tue-Thur." I don't think they get any benefits.

I'm not recommedning all DLCs but if someone's most important consideration is working when they want, the ones we've used seem to do the trick.
