Pros
When you first start out, things seem really fun - happy hours, community events, supporting entrepreneurs and other community members. Free beer at work. Colleagues are usually nice and friendly when they're not being passive aggressive. Most of the members appreciate the community managers.
Cons
Passive aggressive colleagues, competitive culture instead of a collaborative one. Things behind the scenes are so disorganized, and employees don't feel empowered to change anything that needs fixing - very bureaucratic. The CEO is full of himself and is all talk - seems like the money has gotten to his head. There's a facade of community-building but it's all about filling up the space with people who have bought into the idea that they're going to be hip and cool because they can show off their office to their friends and family. I've heard and seen employees talk about the members behind their backs, and complain about the "customer service" side of things. Hello? That's our job - to help members do what they love.
