7am-6pm four days a week, one day off a week and one Saturday a month from 7am-12pm. Most people only work 36 hours a week.
Stable, they expect you to stay way later than you're scheduled to half the time though
Horrible, long and late days all the time.
They are tolerable
The hours vary at different locations. At my location, the hours are really nice. Most people come in at 7:30am and leave absolutely no later than 5:00pm. My hours happen to be 8:00am to 3:30pm.
