Pros
Great progression path. There is ceiling on promotions, if you want it they will give it to you if you earn it. The benefits package is very great compared to other big companies out there. Pay is great as well with many different opportunities to make supplemental pay whether its job bonus or perfomance based, and they usually have a merit raise at about 3% yearly.
Kontras
Family time. This businees is non-stop, especially in the office. Office personal normally work a schedule like every other weekend off or 11-3. So so day on you have a week on call but either way you still have to be accesible by phone or email 24/7. If your a field personnel on land that treats the rig operations you work a 7 days on 2 days off, 7 days on 3 days off type of schedule. Now all of the mentioned above scheudles can vary slightly depending on your location. Now I currently work offshore and find it to be the best schedule so far if you can do the time. I work 14 days on 14 days off. I've also worked 28 days on 28 days off. Either way your only working a half a year making in excess of six figures for half a year of work. So many people don't make that working a full year. But the downside is you miss a lot of home activities from being offshore.
