Industrial maintenance is a pretty good field. It's a struggle to find people able or willing to do the work, so jobs are out there.
I'm in plant maintenance, I'm actually sitting at work right now. I have a two year degree from the local community college in Electro-Mechanical technology. I've been here just over 9 years. My annual base is $61,745, today's paycheck put me over that for the year. That's mostly because of the 25 straight night shift shutdown that I worked in the spring though. I've been an overtime whore ever since I've been here up until the last few months. A new woman in my life has slowed that down though. Lol. I haven't grossed less than $80K the last 6 years though. Two years ago I grossed over 6 figures, but that took 1K hours of OT, including 43 straight night shifts.
Most maintenance here works straight days, but we have small crews that work a 12 hr schedule that rotates between days and nights. That's what I'm on. It's a 4 week rotation. In those 4 weeks I work 7 day shifts and 7 night shifts, (4 nights, 3 days, 3 nights, then 4 days) We work two weekends, then off two. We also work holidays. Hell or high water, we're here. I had a straight day job doing the same thing, off MOST weekends and holidays. But being a semi-young single guy the money I could make on shift was too much to pass up. One day I may want to get back to a M-F job but for now I'm happy with where I'm at. (Feet propped up on the desk, watching TV, and surfing hardline).
