Also really depends on the frequency and reason. Did something go horribly wrong once and does this one-time effort fix it or gives enough time for a decent solution down the road? Sure, I’ll put in some extra work. Don’t look for me though when it’s resolved, I’m on holiday with all the overtime I should’ve gotten. If it’s a structural problem because management wants to squeeze as much money out of their employees and refuses to hire enough people… Fuck that. And yeah, corporate uses the first thing as an excuse, luring you into staying longer “one more time, we really can’t do it without you”.
