CCMH, we started a similar thing here last October. Most of our trucks run 12 hour shift. We have 1 truck that is a 24 hour truck. I am one of the ones that ended up getting the gig. We also are only paid for 16 hours. The management did a lot of leg work looking into this. Apparently, according to the labor board, it is legal to do. The only thing is that they have to pay us for any time that we are up during "sleep hours". If we get less than 5 hours consecutive sleep, then they have to pay the full 24. So, according to all the county lawyers and everyone else, this is a fair and legal practice. Do I agree with it, probably not. But, if they were going to pay us for the full 24 every night that we worked, I would get a $15,000/year raise. So in the interest of budget, this is what they have done. I hope this answers your question. If you want the legal answers in print, I can try to get them for you after the holiday.
