In the USA, I'm pretty sure that violates federal contracting rules. Maybe you ought to report them. As I understand it, they have to pay overtime if you work 48 hours in the week. The typical expectation is thus 47 hours. Perhaps you would not have been directly billed to the customer, possibly making the rules inapplicable. Unpaid overtime is something I expect much more from employers that are not doing government work, particularly the game industry. I've found a very different situation at a federal government contractor. Normal weeks are 40 hours, it is rare to work beyond that, and any extra work means extra pay. BTW, see my "Who is Hiring?" post if you wrote an embedded OS.
