      Don't blame me

      Pros

      The benefits package is pretty decent, and you get a lot of vacation time (4 weeks to start). Also, because they have a lot of turn-over, your job is pretty secure because they don't want to lose you.

      Cons

      Your four weeks of vacation time includes any sick time. Also, they only have 6 holidays. Your bonus is based on how the business unit performs as a whole, and has no reflection of how hard you work. If your business unit underperforms, you could end up with no bonus. Management tends to point fingers down on their employees when things aren't performing smoothly, passing the blame onto their staff instead of taking responsibility for their bad management. The company also underpays their employees, especially in the Boston area where the medical markeet is extremely competative.

      Great work-life balance with supportive management

      Pros

      Provides excellent work and life balance as well as clear directives and communication for set goals and expectations between the management and staff. The staff are encouraged to input their concerns and to point out areas for improvement, most of which are implemented in one form or another depending on the urgency/priority. As with any job, you will get what you make of it.

      Cons

      There were some talks about limited upward mobility amongst the staff, but I didn't find that to be the case.
