When I was in AZ a couple of years ago they circumvented it by having 4X10's off on Saturday while everyone else worked, then having 4X10's come in on Sunday voluntarily. If it's a station by station thing I'd be surprised. Most likely a state law thing.The double time thing is based on the area your station is in. My old station always made them 5x8. The station I'm at now paid them double time on Saturday
