Never seen a single hour of that extra time either paid back or returned to you? Time to go. However it will require everybody to do their part to defeat the system.
People change companies frequently, but all the companies my friends work at now have the same set of issues. Then there are friends who quit the industry and got proper jobs. They just laugh at the whole thing. Granted they have a different kind of bullshit to deal with (bureaucracy in code, formal development) but the working conditions and remuneration just don't compare to gamedev so none of them returned and they think it was a good trade.
