Pros
The ability to self determine work/life balance is great. I don't think everywhere in the company is the same but at Corp. headquarters most managers are very supportive of work/life balance. How, when and where I get my job done is up to me as long aslong as it is high quality and on time. Management is very supportive of continued professional growth in your given field. Some operating companies even require 40 hrs per year of continued education. The company is fully committed to safety and high ethical standards. This is not seen in many other energy companies.
Cons
If you are not an engineer it can be a challenge to move from position to position or across operating companies. The engineers are the most visible and given opportunities (structured and non-structured) to grow and expand skill sets that other carreer tracks are not given.
