PHCC chapters

Union or open shop?

Union

Run by a joint committee run by the United Association (UA) local and union contractors. You apply to the committee, take an aptitude test and an interview, and wait on a ranked list. The committee sends you to its contractors.

Pay is a set share of the union journey-level rate and steps up on a schedule. Classes are nights or week-long blocks, usually paid for by the program.

Open shop

Run by PHCC, ABC or a single plumbing contractor. You usually get hired by a member contractor first, and the contractor enrolls you.

Your employer sets the pay and the raises. Classes are nights or weekends, and some programs charge tuition.

Pre-apprenticeship

Start on a crew

Licensed contractors hire helpers with no experience. Keep a log of your hours and employers; many programs and license boards count them. If you'd rather learn the basics first, 2 schools in Colorado have plumber programs.
