This has happened at my company that is now 35 people. Too many managers that have fractured communication. Getting things done was easy when there was 10 people.
This can happen even with small numbers of managers. It only takes one territorial or poorly-communicating asshole to fracture a broader organizer. If anything, a small number of managers exaggerates the damage that one bad manager can do.
How many managers do you have for this to be a problem at a company of 35?
