Pros
As a field technician a Pro would be the Perks, you get a top of the line, 4x4, 4 door pickup with a tool box topper, field expense credit card, they pay for the fuel you use and let you drive the company truck on your time off, give you a panasonic toughbook, a company smartphone, if you have your work done and have prioritized well then you have no set work schedule, manager stops by about once a quarter and takes the local region out to eat for a Q&A session. Pay is pretty good, considering.
Cons
Management is difficult to work with, this is to include HR. There are only 3 people running HR for the USA division but truly on one guy is in charge of HR for about 500 individuals and he has little man syndrome. They all say to use the "Pason Culture" in difficult times when dealing with a co-worker or a manager, but really it means nothing, and is just the perception pushed to the employees that you have rights and that you will be heard. But sadly when you speak up about inequalities and favoritism and the workload, prepare to have your workload increased because you made your regional manager look bad and well if you burn out no big deal, they have people lined up to take your position. The hardest part is dog eat dog culture of the field techs, if you don't bow down to a senior tech's "experience and know-how" just plan on being shunned from the group. Then when you are getting slammed with work, no one comes to your aid. A field tech is on call 24/7 and is expected to go out on the route when there are no calls and visit with the customer and check on the installed equipment, then after being out 4-8 hours you are expected to take all the night time phone calls and usually usually an emergency call out. When and if you get back to your house with getting another phone call you get a couple hours of sleep and your day starts all over again. The big problem here is getting enough sleep while you are on call for 14 days straight, thats right you heard me right 14 days of 24 hrs a day. Then yo get about 3-4 days off then another 14 days straight. Housing is always an issue in the oil field, and their monthly compensation for cost of living in the boom towns is far below what it takes to live up here, so you end up spending a lot of your income to take this job. Again small man syndrome is in charge of that decision.
