I did some job-searching yesterday and the jobs I could get pay roughly what I'm making now (shocker, I know). But the big problem is I pay $100/mo in rent for work housing now, and a new job would be $800/mo with a roommate, so overall a drop in earnings. Although I do consider that a regular 8-5 schedule is way better than the permanent night shift/holidays/weekends work that I'm on and that in itself has some amount of value. I have to sacrifice a lot of social outlets for this job (difficult when you're single and worse with a family) and that has me feeling pretty lonely.
But especially if I hope to retire in 12-ish years, I think I'm pretty well stuck here because I can't afford to sacrifice a penny of income. As bad as morale is here with no opportunities for a raise and new hires making more than veterans, that's largely the reaction a lot of people are having here, that they're pretty well stuck.
Adding to it there's a certain fear that if I changed jobs and the economy got worse, that I would be taking on the higher risk of getting laid off as that "last in, first out" employee.
