Nobody gets fired over the mistakes they make unless (1) they make the same mistake over and over again (2) they have an attitude when people try to help them and/or give them feedback.
If you're in an environment where mistakes immediately lead everyone to think on how this reflects on their performance (without factoring in what the mistake was, what happened, how can you learn from it) an interesting thing will happen: people will get better at covering their mistakes. New people will struggle to adapt and old people will burn out. Guess what happens in the long run? The whole operation will collapse. If you are in one of these toxic places GTFO - no amount of money is worth your mental/physical health.
