I work at a financial company (200B assets) writing software to analyze bond market. When pandemic started and stock crashed, our software didn't expect such a market crash (obviously, it's called a pandemic ...), so I had to work 80+ hours to get it fixed as everyone else who worked on the application already left and the new people didn't have any clue. Fast forward to the post-mortem phase which also happened to be annual review time, my manager told me I am a toxic person and I made everything worse during the crisis.
To make the matter worse the night when everything was fixed, I was on my way home at 3:30am and I got a speeding ticket for going 60mph over the limit. I fell asleep behind the wheel, thank God I'm still alive.
I left that team immediately, and exactly one year has passed and they haven't been able to find another person to replace me but what bothers me is they promoted that manager because I left and he got all the credit.
In summary, I will never ever work over 40 hours for any company.
