The rewards of apprenticeship training are the good wages and benefits you receive as a skilled craftsperson. Residential carpenters belong to the United Brotherhood of Carpenters and Joiners of America, the largest building trades union in North America. You'll be working under the protection of a union contract, probably with health insurance and pension and welfare benefits. In the long run, it pays to be the best you can be . . . a residential carpenter trained through apprenticeship!
