The most current union pay scales for construction trades are available from local union halls. Some of the union halls may have active websites on which they publish the pay scales.
Establishing union wages promotes skilled trades and protects the workers within these trades. Unions hire and train individuals who wish to learn a trade through programs called apprenticeships. Once a worker has demonstrated skill within a trade over a number of years, the union promotes them to journeyman status. Each year of experience grants workers an increase in wages, up to a maximum wage set for each trade by the union. Cost of living adjustments are also applied to union wages periodically.
