      Very stressful environment, but flexible schedule and cool coworkers

      Study director
      Recommend

      Business Outlook

      Pros

      You get a lot of leeway with your schedule in the study director group if you get your work down without complainants and are available when the lab needs you. WFH. Coworkers are alright, I've had a lot worse.

      Cons

      No actual bonus, but they include it in the "total compensation package" value and use to hold the possibility in front of you to pull as much work from you for as little pay as possible then pull it away at the last minute. Very stressful. Understaffed. Systemic issues that will likely never be fixed. Run by venture capitalist firm who is doing everything to squeeze every last cent from the company. Cutting cost is the priority now rather than good science. NAMSA used to do "good science" and now, it's just "science". It would be bad science if the employees didn't have integrity. The top leadership doesn't seem to understand the day-to-day activities and how their decisions affect the employees. Burnout is at an all time high.

      Great team with learning opportunities,

      Small animal vivarium associate

      Business Outlook

      Pros

      Good team environment, always something to do, a lot of learning opportunities. Promotions can be slow, but raises and job movement are based on performance and merit so you get out what you put in.

      Cons

      As said above, promotions can be slow at times. But internal movement opportunities make up for that.
