A childhood friend made THHN half his life, learned his machine: had the burns to prove it. Money was good, union was good, one day the company moved to Korea. So my buddy got his LPN license and goes to jail every day to do meds. He is the kind of guy that can do a job like that with a smile. Money is good, union is good, he says it beats making wire in the dark. Each to his own, YMMV.
