if I had to guess plants are paying around $40 an hour +\- $5. Use $40 as a reference.. that's an 83k a yr base for a day job. Ab 97k shift work (with built in OT). A little more for shift differential. Doesn't take much OT for a shift worker to get over 100k. I'd bet most are making 130-150k with OT. But at times u are right... they do own you. I haven't had but one day off every other week here lately. Haven't been fishing since beginning of April
straight job = 2080 hours
shift work = 1976 reg pay, 208 built in OT, 10 holidays and 1 birthday (that's how it's set up at my work.. I know some places have changed recently) and of course sometimes u work holidays and get extra pay
and don't forget quarterly and yearly bonuses
