Pros
Global environment and a lot of opportunity to learn and stretch yourself professionally. Every assignment, foreign and domestic, prepared me for the next assignment. The 33 years of valuable experience helped me land another significant opportunity with a larger more prestigious multi-national corporation.
Cons
You have to be sure that you always have your CV updated and "out there". Do not rely on the standard Fluor CV. It is useless in the job world. Go ahead and market yourself just in case something happens so that you are not unemployed for a longer than required time. When you get the lay off notice it is generally only two weeks or immediate depending on your role. There is some significant back stabbing that goes on in the office culture. People will crawl over you and lie to make sure that they continue to try to climb the ladder. Significant lack of ethical standards abounds. You have to watch out for yourself all of the time and remember that you really do own your destiny.
