Depends on how much overtime they have to factor into there. In the short term, especially for short term demand, it's going to be a lot of people making time and a half or 2x more likely than not.

A new shift will take a while to train up and temps are... ugh... don't even get me started about the sort of people temp agencies send. We had some that only lasted a day for not listening and doing stupidly unsafe things. One of them nearly hit me upside the head with a piece of glass because he wasn't paying attention to where he was swinging it. That was his last day on the job, for precisely that reason.
