I am an on call employee for a company. I am constantly working for them and have pulled scheduled and non-scheduled overtime for them. But I've been wondering how legal some of these shifts have been. For example: I worked a 12 hour shift, then had an 8 hour off period, then returned to work for another 8 hours, had a 7 hour off period, then returned to work again for a 16 hour shift, had another 7 hours off, then returned to work once more for another 8 hour shift. And recently I'm scheduled to work an 18 hour shift.
I have to draw the line somewhere. Long hour shifts with no sleeping breaks is extremely hard and stressful on a body.
