I fell into this game as a youngster, but pretty quickly discovered that there's no reward, the extra hours rarely earn you pay, appreciation or even get noticed.
Recent years have been characterised by the "we're breaking records, month after month, but the arbitrary targets we set were even bigger so we have failed and can all have just a little less than inflation this year" approach. None of the extra hours worked on increasingly rare occasions make the slightest bit of difference. The ultra-rich owners of the parent company get ultra-richer, the workers actually making them their money get a small real-terms pay cut each year as a reward.
So yes, giving your free time to help rich people get richer is a mug's game, and disaster-recovery aside, I'm not playing any more.
