Pros
Your colleagues. Pace inevitably attracts talented and enthusiastic young people who are great to work with and lean on. You will learn a lot if you are willing to put in the time and to stomach indignities. Few employees remain happy here after three years but it's a good stepping stone to other galleries and institutions because so many junior staff leave for better work elsewhere. If you're lucky, you'll receive good compensation and benefits. If you do, however, it's likely that you're working for the nastiest people and much of that money will go into your poison of choice, or a therapist.
Cons
The HR department is purposefully kept weak and understaffed, enabling rampant emotional abuse from diva directors whose work grows less and less relevant. Pace suffers from a toxic atmosphere in which frazzled middle managers become the conduits of the insecurities and fickle temperaments of senior sales staff. Resources are devoted to coddling these dinosaur dealers while entry-level staff [esp. gallery assistants and accounting] are underpaid and overworked. Ridiculous turnover and depressed morale makes it difficult to collaborate and delegate. The impressiveness of the roster wears off after a while once you notice how little is being done with it. This is a blue chip clearing house - you'll find more exciting and creative programs elsewhere.
