Being a junior myself before all I can say with others that came after me was:

- Keep your head down
- Don't take everything as an offense
- People are rude or angry, but that's just how we are: we deal with normal users' BS everytime that we just wanted a break.

"Keep your head down" has to be some of the worse advice I was ever given. Not only is it unprofessional, it's essentially saying "shut up, the big boys are talking - know your place, trash".

@junon This.

Though being too outspoken or too different can easily get you ostracized or fired. Know your audience.

If you have to keep your head down then either you're working in a terrible environment or need to listen more and keep your arrogance in check.
In any case, not speaking up is terrible advice.

@junon I wouldn't really say that, a year ago a junior was complaining too much about how a senior was always up in their ass and most of us thought it was the senior's fault.

Later on we found out this sack of shit of a junior was just causing drama for the senior for no absolute reason - the guy was just reminding them of their workload not being done.

Also another case was when a junior had complained about our CQ being too strict (surprise surprise it wasn't - the guy just doesn't know how to code standards).

So my "keep your head down" was a little under-explained.

@caramelCase Be that as it may, that's a corner case - most of the time "keep your head down" is a way for a manager to assert dominance over their subordinates. It's an incredibly toxic, well known line to say, especially in big top-down corporate environments.
