But completely honestly, why did you even develop this kind of culture in the first place? Don't you think you should have prevented the whole situation in the first place?
Heh, that's easy to answer - it's because I was an idiot!
Of course I should've prevented the whole situation in the first place, but I wasn't on the ball enough to realize it was a problem. I wasn't consciously trying to shape company culture at all, which is why it developed on its own in a suboptimal way.
It happens all the time, and it can be essentially invisible to management at larger companies. People get close. Cliques with their own sub-cultures will develop, HR-unfriendly and perhaps legally-actionable things will go on behind closed doors when everybody in the room is friends with everybody else.
Nobody will really notice or care until someone with a different worldview starts having to work closely with them and stuff starts bleeding through.
When it goes on for too long, people may get angry and resentful when trouble starts, and then you have a much quieter but more insidious mess...
What? No, I've never seen this happening from the inside! Of course not! I'm a perfect angel!
