Culture is the behaviour you tolerate
Every organisation has a stated culture: the values on the website, the words in the onboarding deck. And every organisation has a real one, which is something quite different. The real culture isn’t what you say you value. It’s the behaviour you’re willing to tolerate — especially from your best people, and especially when it’s inconvenient to address.
Words are cheap; tolerance is the signal
You can write “we value respect” on every wall in the building. If a high performer treats people badly and nothing happens, the team learns the actual rule in about a week: results buy you a pass on respect. The stated value is now worse than meaningless — it’s a visible lie, and people calibrate to the truth they observe, not the one they’re told.
Culture is taught by what gets through, not by what gets said. Every behaviour you walk past, you endorse.
The hard case is the talented offender
It’s easy to uphold standards with someone who’s struggling anyway. The real test is the person who’s genuinely good at the job and genuinely corrosive to be around — the one whose output you’d miss. Tolerating them sends the loudest possible message: that the standards are negotiable if you’re valuable enough.
Most cultural decay I’ve seen traces back to a version of this. Not a dramatic failure, but a slow accumulation of exceptions made for people who were “worth it,” until the exceptions became the norm.
Setting the standard is an active job
A culture doesn’t hold itself. It’s maintained by a thousand small decisions about what’s acceptable:
- Address the behaviour early, while it’s small and the conversation is easy, not after it’s defined the team.
- Be consistent regardless of performance. The standard that bends for your best people isn’t a standard.
- Remember that the team is always watching how you respond — and learning what’s really allowed.
If you want to know an organisation’s actual culture, don’t read its values. Look at the worst behaviour its leaders consistently walk past. That’s the real document, and everyone on the team has already read it.
