Pros

Good cafeteria, good people for the most part; I’ve made some good friends; and some of the leadership nearing retirement age are also very good.

Cons

No clear communication from anyone, will be cut on a dime. And zero work life balance.

Pros

Decent pay, good benefits, many great coworkers, solid work life balance

Cons

Technology old and boring. But more concerning, reported very disturbing issue about a coworker through the ethics channel and received little to no follow-up from HR, which was disappointing. Situations like that should be taken seriously and addressed transparently. Management consistency was also an issue—after one difficult manager was finally let go, I was reassigned to another with different problems. At that point I decided it was time to move on.
