Pros

Lots of PTO once you earn tenure (18 days to start, 23 at 5 years, 26 at 10).

Cons

Senior leadership has had a full turn over and everyone is scared to say anything. The only way for groups to get more headcount is for current FTEs to work crazy overtime to demonstrate the ‘need’.

Good money and benefits, good location.

Not health work balance and environment, poor systems, not driven by technology, heavily excel based processes, not open for modernization, lack of people management skills for higher level managers above.
