Pros
All photography all the time. Everyone who works here is highly engaged with the field internationally and is very committed to the organization. A very active place with lots of events and chances to learn more about photography, interact with artists/photographers/authors/curators, and gain valuable and unique insight into the workings of a publisher, gallery space, and non-profit all at once (not a lot of places have that mix). Many people have been here quite a long time, which could be seen seen as either a pro or con, but it's worth noting that some people find serious job stability. People often take on several roles within their position. This could be seen as a con (see below), but also a pro in that it's possible for a highly motivated person to take initiative and develop their professional skills more than at other organizations. There is also lots of cross-departmental work, no matter what job you have. You know everyone in the office and have worked with them at some point. Everyone is genuinely nice, and it's like a family even when there's professional dissension.
Cons
A large portion of the staff is overworked. This doesn't just relate to workload (which is all NGOs and most professional jobs in NYC), but also people's roles not being well-defined and often encompassing what would be 2-4 positions at another organization. No one does just one job and does it well. This is mostly a result of too many projects happening at one time in relation to staff resources and budgets, as well as projects not being thought out thoroughly and in advance. There isn't much room for career growth, unless you're in the editorial department, where there's a little more flexibility (This is probably because these jobs are the most specialized and therefore, the most valued). Staff morale can be low because people feel overloaded and like it's nearly impossible to do a good job. In a staff full of dedicated people and perfectionists, this is a real downer!
