Pros
Good pay, overtime paid at 1.5 your salary hourly rate, good benefits, satisfaction of completing a large project, always working with blue collar/union workers so communication is more laid back and less professional, 25 days of PTO when you first start but between projects you also get time off
Cons
Always on the road in remote locations where power plants are located, projects can be anywhere from 1 week to 4-6 months, when on a project you will work either 6 days a week 10 hours a day or 7 days a week 12 hours a day and could be either on dayshift or nightshift, some managers will work you to death and want to try and keep you in field service as long as possible and will put contingencies on moving you into a new roll, always new hires being sent to projects to work with you with very little experience, they seem to hire just about anyone for field service engineer position
