Pros
Arena offers a great relaxed atmosphere and doesn't interfere with my personal life. The stress level is very low and management is usually pretty understanding of "life-matters" (doctors appts, vacation time use, etc.). Freedom to come in, take lunch, and leave when you want, as long as you get 40 hours/week in and get your work done. Benefits are decent, but could be with a better healthcare network.
Cons
The environment at Arena is awful. It is very dreary, and most employees keep to themselves so there is not too much interaction which makes for a very sad, depressing day. The pay is low compared to other bio-tech companies in the area, and there is absolutely NO room for employee growth, both in level of position, and salary. There are no incentives and no bonuses which also contributes to the sad, dreary work environment. The responsibilities and work load held among non-management employees is pretty much equal which makes the salary differences hard to understand. Harder working employees should be rewarded, but never are.
