And then you use a generator and vault, but there’s some stupid caveat like “you can’t use the ^ character.”

That’s pretty normal for meh-tier kind of jobs in the US, though usually you “graduate” to two weeks sooner, like after a year.

In many workplaces there’s a culture of taking as little as possible of the allowed vacation time. Sometimes it can lead to a small bonus when those days get “paid out” at the year end. Other times, the only encouragement is just pressure from the boss or coworkers. Note that there is neither a legal minimum for vacation days, not a requirement that employees actually use the days they have.
