Management will run you into the ground during busy times, you could work 8 hours one day and 12 the next. On several occasions I ran into problems getting the windshield out (replacing a windshield is not as easy as you might think) and tried to call management only to find out they were already home for the night already and the next closest installer was 45 minutes away. Worked till 8-9 pm on several occasions. Also the surveys that effect your potential weekly bonus do not work in your favor (it's easier to lose the bonus than it is to get it). I believe this is because more people would rather complain than give positive reviews.
They talk a lot about the importance of work life balance yet don't care how much overtime you work so long as they are home by 5.
