Low stress work environment with good work life balance. Management goes out of their way to get to know you. Good benefits. Probably my favorite place of employment that I've ever been at.
They will give you green paper in exchange for labor. They provide great safety equipment and will purchase supplies as needed in the field, they pay for certification and necessary credentials to perform work.
Cons
Work description changes real-time depending on how PM's day is going, field work research and preparation do not exist, micromanaging is the name of the game.
