They have Salary and Per diem positions. Both get insurance. I am salary and still get paid shift differential and overtime. Allowed to use personal card for everything but flights (this job involves a lot of travel) They match 20% of what you contribute to you 401K. Low Stress, full time is 4 days a week.
Cons
Unless your zone is busy expect to fly/stay overnight at a location 80% of the time.
No real ability to "move up"
