General carpenter
A day looks like: Framing, formwork, finishing; residential and commercial sites. Very hands-on, visible results daily.
What stops people: Easy to start, harder to reach top pay without specialising or going union.
Downside: Pay ceiling is lower than electrical or plumbing unless you move into site supervision or your own company. Outdoor work in every season.
Steamfitter / pipefitter
A day looks like: Welding, threading and fitting high-pressure pipe for heating, process and nuclear systems, mostly on industrial sites, with eight weeks a year in trade school, paid throughout.
What stops people: Getting into a UA Local 46 or 787 intake, or finding a non-union sponsor. Intakes open only a few times a year and are competitive.
Downside: Five years to the ticket. Industrial, refinery and nuclear sites mean travel, shutdown schedules and long stretches away from home.
