How do I learn the unwritten rules of a salaried job?

Crossing into salaried work is a real change, and the hardest part is not the tasks. It is the unwritten rules nobody explains. How people talk, when to speak up, what is expected beyond the clock. You are not slow for finding this confusing. You are reading a language that was never written down. The way you learn it is by watching. Find one or two people who seem to move easily in this world and pay attention to how they do it: how they handle a meeting, an email, a disagreement. Most unwritten rules are just patterns, and patterns can be observed and copied until they become yours. You are not pretending. You are learning, the same way you learned every other job. Pick one person you respect and watch how they operate this week. Copy one small thing they do. The professional world is not a locked door with a secret key. It is a set of habits, and you can pick them up one at a time.
