Pros
The pay and benefits are great.
Cons
Not a lot of room for job growth and development unless you are a white male who likes to play golf and part of the "old boys'" club. I worked in Public Affairs for 3 1/2 years under one of the most tyrannical bosses one could ever imagine. Yelling, degrading comments, belittlement and snubs for quality assignments were all daily occurrences. I was even physically pushed once when my supervisor was having a bad day. I went to OMBUDS (an internal mediation service) about her, and their response was, "I thought she was getting better." Funnily enough, this was not her first time harassing her direct reports. She was demoted once before for the same thing, and has just been demoted again for doing the same thing to my successor. Failure to fire these type of people (yes, there are more of them) from this company is a great risk to employees and stakeholders alike. My parents have each worked at Chevron more than 35 years and have had their share of "horrible bosses." Beware.
