i am part of local 38 san francisco plumber and pipefitters. the pay is about as high as it gets for union trades unless you're gunna do elevators or a crane operator. but work is kinda spread out right now. like right now i'm laid off until the end of the month, but going back to build a hospital which will take a couple years. it's been so slow since 08 that we have been only taking like 2 or three apprentices a year in the north bay program. and yeah it's a lot easier if you know someone
