I did actual OT only once and that was when a piece of my code did some havoc in production. Even though I agreed to OT because I felt responsible I should have just ignored it; no one told me that a group of people is going to push the code during the long weekend, no one told me that I should be on standby and my request for code review has been ignored. The boss actually refused to give me a day off for this whole ordeal (a law in my country; if they call you in on your day off they're obligated to give you a whole day off no matter whether you worked one hour or eight hours. If I wanted to make it right I'd have to take it to the court so I just decided to find a better employer instead.
