You join a new team and notice that everyone replies to the manager's messages within minutes. Nobody told you that was expected. You replied four hours later, and the response was cold. Now you wonder what other rules you are missing.
What are unwritten rules?
Every workplace has a gap between the official version and the real version. The unwritten rules live in that gap.
Unwritten rules: The informal norms that decide how a workplace really runs: who gets heard, what gets rewarded and how things get done. They are not in any handbook. They show in what people do again and again when no policy tells them to.
The official version
- "We have an open-door policy."
- "We move fast."
The real version
- The director's door is always closed, and you book time through an assistant.
- Every project needs three rounds of approval.
How to spot them
You spot unwritten rules by watching what people do, not by reading documents. Watch three patterns.
- Who speaks first in meetings: And whose ideas get acted on.
- What gets praised: And what gets quietly ignored.
- Where real decisions happen: In the all-hands meeting, or in a smaller conversation beforehand?
Once you notice a pattern, check it. Ask a trusted peer: "I have noticed X. Is that how things work here?" This one step stops you from acting on a wrong guess.
Two mistakes to avoid
The first mistake is to trust the handbook as the full picture. It gives you the official version, which is often incomplete.
The second is to copy what senior people do without knowing the context. A senior colleague might skip a meeting because they have earned that trust over years. If you skip the same meeting in your first month, it means something very different.
One rule to remember: When the stated rule and the actual behaviour do not match, the behaviour is the real rule.
This is not about being cynical. It is about being accurate. When you know the real rules, you can choose where to spend your energy and how to build trust early.
