Enterprise A-Z: Unwritten rules
The Invisible Operating Manual
On the org chart and in the policies, your company looks one way. In real life, you learn quickly that some things “just aren’t done,” some phrases land badly, and some topics are always taken offline.
That gap is the domain of unwritten rules.
Why unwritten rules matter
Every organisation has them:
“We don’t surprise the CFO.”
“Bad news goes up fast – or gets buried.”
“We don’t say no to key customers.”
“We don’t challenge X in public.”
These rules aren’t written down, but they heavily shape what is possible. If you ignore them, you burn energy running into invisible walls. If you see them clearly, you can decide which ones to work with – and which ones you’re willing to gently test.
What unwritten rules actually are
Unwritten rules are patterns of behaviour that are so consistent they may as well be policy. You’ll spot them in:
The stories people tell about “how things really work here.”
What gets praised or punished, regardless of what the values say.
The topics that reliably get pushed to a smaller room, or to “next time.”
Some rules are healthy – they protect trust, integrity, or financial stability. Others quietly block the very shifts your role exists to make.
Your job is not to blow them all up. It’s to decode them and then choose your moves with your eyes open.
How to start
Do some quiet noticing. Over the next few weeks, treat your workplace like a case study. When something moves quickly, ask yourself why. When something stalls, ask what unspoken rule might be at play. Pay attention to phrases like “that’s just not how we do things.”
Sort the rules into “work with” and “work on.” Make a simple list of the unwritten rules you’ve observed. Which ones can you respect and even use (for example, “we prepare leaders well before big meetings”)? Which ones are getting in the way of what you’re here to do (for example, “we never escalate bad news until it’s a crisis”)?
Experiment with one gentle challenge. Pick a single unhelpful rule and design a small, low‑risk way to test its edges – perhaps by naming an issue a bit earlier than usual, or asking a question in a forum that normally stays silent. Anchor it in the company’s stated values or commitments, so you’re not just pushing for your agenda; you’re aligning practice with what the organisation already says it wants to be.
You will never fully escape unwritten rules; they’re part of how any human system keeps itself coherent. But when you can see them, you can stop being blindsided by them – and start deciding, consciously, which ones you’re willing to live within and which ones you’re willing to nudge.
