Indeed, when I worked at EA in BC we were promised comp time for working 'coverage' (overtime) and I even got into trouble for refusing to work on Labour Day! The comp time fizzled into nothing because they fired the Development Manager of our group on the DAY of shipping the game. He just disappeared along with all of his promises. I alone got paid for the overtime because I refused to work TFT (temporary full time - which they pressured me to do) and instead was a true contractor.
