There are a lot of industries where if you aren't at work before and after the boss is and aren't there 50+ hours and promptly answering calls and emails all weekends, you will not ever be promoted. A lot of my friends in finance are going through an existential crisis due to the weight that this mandatory brown nosing has on their well being, despite the decent pay. A lot of them feel trapped in their job, that they can't transition to a better industry with a better culture without basically resetting the last five years of their careers with no guarantees of making it back through the rat race, or that it will be culturally any different at all.
