      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.
