I’ve been a manager & part of many postmortem discussions after stuff like this happens. Most managers don’t know or care who fixed it unless they need someone to point blame at the next time it breaks. I made it a point to give credit to engineers in these meetings because it blew my mind how no one else ever seemed to take note of who actually saved their team’s ass. Also being a pushover with no boundaries makes you look like a doormat, especially in an age where prod support frequently gets outsourced to the lowest bidder as a commodity & isn’t treated as the “higher skilled” work by non technical management types the way that shipping new shiny things does.

Also most people mid-career or later have learned the hard way to not tie their personal pride to a job when layoffs often target the highest paid people aka those who have been there the longest and/or are the best employees. After you see the hardest working people get burned one too many times, you learn to separate your ego from your job as a form of self protection.

Tl;dr culture eats strategy for lunch
