I am employed as an HVAC technician by a large company contracted to provide maintenance services for a NJ public school district. The contract requires a full-time HVAC tech onsite. I was told that they only need to pay me for "wrench time" on specific tasks. They will not even pay me for taking my tools off my truck-ONLY for "wrench time" spent on say an air handler. Can you please clarify how a Master HVAC tech, Master plumber, or Master electrician should be paid in this type of case? Is the company required to pay the prevailing wage for each trade for 40 hours per week or just by the "job"? Again, the contract calls for the provision of a Master HVAC tech, Master Plumber, and Master Electrician to be onsite 40 hours per weak, and NOT for the provision of "HVAC service" or "Plumbing service" or "electrical service". Thank You, Carlos
