Pros
Decent work-life balance with options for teleworking, taking leave, and having family time. Good medical plan and decent benefits, if they don't completely cut them out. As long as you can keep your head down and do what your told without asking to many questions, you should be fine.
Cons
Everything is based on internal politics, including management positions, performance reviews, and pay raises. Those in charge are very unprofessional and they seem to enjoy keeping that way. No way to get meaningful work done. They seem to have no money but can spend on meaningless things and areas. Management willingly violates the core values of the company without thinking twice. I have no idea how the place is still open. My advice is to stay clear of wreckage known as Battelle Memorial Institute.
