They manage managers. Per every ~8 people, you need some sort of a map/reduce operation. That is a manager. An organization is essentially a giant map-reduce hive mind. Some managers are there due to them just cruising slowly up the chain. Management is a really hard problem. There are very very few managers I have met in my entire life that I would work with them again. Some just love the power of ordering people around. Some are just plain assholes. Seriously, life is too short to be treated like shit.
