What is the difference between a BTJ and a MESJ pipefitter relative to what paragraph in the National Service Agreement?

The difference between a BTJ (Building Trades Journeyman) and a MESJ (Mechanical, Electrical, and Service Journeyman) pipefitter primarily lies in their areas of expertise and the types of work they are qualified to perform. According to the National Service Agreement, this distinction is outlined in paragraph 5, which details the specific classifications and scopes of work for each type of journeyman. While BTJs typically focus on general building trades, MESJs are specialized in mechanical and electrical systems, reflecting the different skill sets and training associated with each classification.
