NOTES:

FindingIntent2009 c 36: "(1) The legislature finds that dishonest construction contractors sometimes hire workers without proper licenses, certificates, permits, and endorsements to do electrical, plumbing, and conveyance work. This practice gives these contractors an unfair competitive advantage and leaves workers and customers vulnerable.
(2) The legislature intends that electricians, plumbers, and conveyance workers be required to have their licenses, certificates, permits, and endorsements and photo identification in their possession while working. The legislature further intends that the department of labor and industries be authorized to require electricians, plumbers, and conveyance workers to wear and visibly display their licenses, certificates, permits, and endorsements while working, and to include photo identification on these documents. These requirements will help address the problems of the underground economy in the construction industry, level the playing field for honest contractors, and protect workers and consumers."
