Plumbers apprenticeships

program description

Local 38's apprenticeship program is comprised of plumbing, steam fitting and refrigeration sections with two regional training facilities, the Joseph P. Mazzola Training Centers in San Francisco and Santa Rosa.

Apprentices will be paid while receiving on-the-job training, starting out making a percentage of the Union journey-level wage and receiving pay increases at the end of each six-month training period.

Completion of the program takes a minimum of five years. The years are broken down into ten (10) periods. During this time, you will receive on-the-job training.

Students will also be required to attend related and supplemental instructional classes in the evenings, two nights per week (with summers off).

Apprenticeship program graduates gain the skills and knowledge they need to count themselves among the very best plumbers, steam fitters, refrigeration and air conditioning mechanics in the world.
