Pros
Big company that's not going anywhere. Fair pay and benefits. Good opportunity for advancement provided you are well liked. Work life balance is ok, and depending on your manager, they can be very fair. Can work remotely although that seems to be in jeopardy right now. Location isn't too bad. Some smart people working there and the opportunity for productive teamwork is high (depending on whom you are working with). Most of the people (at a certain level) are good, friendly, caring people that are willing to help.
Cons
Current Senior management basically clueless and care little for the worker bees. Cronyism is running rampant at Met. Worker morale is very low at this point and for good reason. Many jobs are being outsourced and people are scared for their livlihoods.
