Deal with the politics and enjoy great benefits (they will spoil you)!
Pros
Benefits are great, Dominion population as a whole is friendly, Dominion cares about volunteer work and giving back to the community, discounts for an abundance of community related activities in which they are sponsors (The Nutcracker, Corporate 4-miler, etc.).
Cons
Started at Dominion without a college degree and I think it truly hurt me. It is extremely difficult to advance without a 'mentor' (someone in management in your back pocket). Life at Dominion resembles a government job in that they rarely discipline low performers (in fact, they usually promote them to simply move them out of a group), the benefits are very nice, and no one leaves (Dom Zombies). HR and senior leaders are currently pushing for diversity. Incredibly difficult to get to the interview stage if you do not fall into a minority category.
