I love most things about my job and hate very little (power plant engineer). Love the schedule, problem solving, learning, future potential, coworkers, job itself and the opportunities. Hate the schedule, burns, coworkers, fiberglass and occasional danger.
I’ve talked with millwrights a good bit and that’s always the biggest drawback. Not sure if that’s what you’re classified as. The union ones I’ve worked with at different plants seem to be in a different state every week or two. One I’m pretty tight with works 6 months on then 6 off for that reason. For those who don’t know, millwrights usually make pretty fantastic money so that’s a viable strategy if you really hustle on your 6 months on.
