If a ceo can disappear for months and still return into a company that isn't on fire,it means they have a functional company. It means there are processes and people in right places to run things in a continuous manner. This isn't as common as people might think. I've seen many companies where people can't survive for a few days without ceo because the position is tied to a million things( often unnecessarily). There's an old saying about owning a business: if you leave and it still runs it means you have a business, otherwise it's just a job

Right, if a janitor can leave the hallways for a week and they're still clean on his return we should let him go

Yes. Your point is?

That the janitor did a good job cleaning the hallways and building enough of a reputation amongst those in the building to not trash the hallways
