The last two places I worked required instructors to be present between certain hours but didn't pay them unless they were actually teaching a lesson. They only paid for actual lesson time, and then barely above min wage. So you could be ready to work from 10 to 4 but then only get paid 2 hours if that's all the lessons you taught. I get it that they're anxious about having enough staffing for unpredictable attendance numbers. And ok, you might get a couple of runs in between line ups. But it just doesn't seem fair to me. A lot of peeps just stew about it until they decide to bail completely. Can they get away with this?
