You might however meet the wrong kind of manager. There are a lot of unfair practices over which there is seemingly no control so long as the results look good. Feedback provided about issues which inhibit proper performance management might not be actioned on for months yet results which might be impacted by these issues are taken into account when making important decisions, selection processes are not always fair as the desired candidate might have been groomed for the position, or there is no selection process at all. Again this is not true for everyone, but there are some managers who are sarcastic or mock you when you ask a question "because you were already supposed to know the answer" even when there was no discussion or training on the topic. I have been present to conversations during which my manager told my colleagues the following word-by-word: "you should have thought twice before having a kid," "you're so clever, what if I call a contact and you don't start at your new job". This is extremely toxic and inappropriate behavior. Not to mention there were a lot of sexually suggestive comments towards female coworkers. This is by no means an exhaustive list.
