Pros
Good benefits for currently employed employees. They cut the pension out last year, so no new hires from here on will be able to get a cash balance pension. They match 6% for 401k and you are immediately vested. Vacation is good and grows with time with the company.
Cons
Inadequate upper level management, Must know someone to move up in the company, Not many vertical opportunities available, Company is strapped for cash with the construction of two new nuclear plants (which probably only 1 of which will be completed), Pay is below average at best unless you are in management, High population of baby boomers who will be retiring and putting financial stress on the company along with other challenges, New CEO is an accountant (Money guy) and makes most decisions solely on financials
