Complaining is a signal that something is bothering us, that something is not working, that something is not as it should be.
And complaining about that one thing should be an activity that is limited in time.
When it’s protracted, it becomes inertia at best, negligence and misconduct in the worst cases.
Taken to the extreme, complaining will become part of a community’s culture. So much so that the object does not matter anymore, and one complains just as a way to fit in and distract.
That’s the danger with many teams.
