I'm a baker, working for a large corporation. I typically work 4 am til noon. When business is slower, like the summer months, our hours are sometimes cut to 37 or so. But during busy times, like the holidays, we can get all the overtime we want.
I used to work for a restaurant. I would go in at 2 or 3 pm, and work until 11 or 12. I'm definitely a morning person, so those nights really took a toll on me!
