After talking to people that currently work there and are part of the union, everything I was told is more or less accurate! However, you're more likely to pull down around 70 your first year, as you start at $25/hour. Shifts are 12 hours, but it's 4 on 3 off. I'm already working 11 hours a day at my office, 6 days a week, so it would actually reduce my time at work.
As for the school itself, it's not a for-profit trade school. Just a local community college. The degree I would be getting would be in
process instrumentation. The ~6 month thing is what I was told by admissions, as I already have many of the basic classes knocked out. If I was starting fresh, it would be a two year degree.
Believe me, I was really sceptical at first as well until I talked to a few people I went to highschool with who did the exact same thing and are making this type of money.
