The longer you work anywhere – and I mean ANYWHERE – the more you see the bullshit and corruption and crappy rules or policies and inequality all over.
For me it has been about the 3 year mark anywhere I’ve worked: once you get past that, you fade away from “damn I’m glad to have a job and be making money!” and towards “this is absolute bulls#!t that [boss] did [thing] and hurt the workers in the process!” or similar
