The throughline I think is that there's no consequence for being bad at one's job. Not to say I'm perfect - I am pretty sure I've been a mediocre employee before, but I've also never been sacked.
That is: I don't hold strangers to my standards or expect them to feel the same way about their work that I do about mine.
I've never been sacked for poor performance, but I have been included in mass layoffs and restructurings throughout my career, which always makes one wonder if they were secretly not meeting some metric.
