Daylight Savings

I've always wondered what people who work the graveyard shift think of daylight savings. In the fall, they have to work an extra hour that night, right? I wonder if they get overtime? (I assume they would, but my copy of the Alberta Labour code doesn't specifically address it). I would hope they'd get overtime! I hated working graveyards enough as it was, but to think you might have to do an extra hour at regular pay is just too much!
