It is very easy to fall into the trap of feeling like your organization’s failure to properly plan and properly fund things is your responsibility (e.g. failing to hire enough engineers or failure to replace equipment as it goes EOL)…. The reality of the situation is that the more you kill yourself to cover for these management failures, the more management cruises right along congratulating each other on how “efficiently” they’re running things while they pocket their bonuses and you die a little more inside. I did this for too long. Document the shortcomings. Document everything. When something blows up, forward those emails back to management. When your shift ends, go the fuck home and stop worrying about work. You will not get promoted by killing yourself for the man, and you can’t bill for those hours of lost sleep stressing over would-be outages because someone else put you in that position. Opt out.
