Does insulator prevailing wage pay overtime in Minnesota?
Over 8 hours a day or 40 hours a week is paid at 1½ times the basic hourly rate; the fringe isn't multiplied. Every DLI schedule says overtime after 8 hours "must be paid even if the worker does not exceed forty (40) hours" (Minn. Stat. 177.42, subd. 4). DLI publishes no weekend or holiday multipliers.
Do apprentice insulators get this rate?
DLI's schedules list journeyworker rates only. Apprentices in a registered program are paid the program's rate (Minn. R. 5200.1070); anyone else on the payroll gets the full rate for the work performed.
Why do some counties have the same insulator rate?
DLI often publishes the same insulator rates for several counties. Across Minnesota, the 87 counties with an insulator rate fall into 16 distinct sets of rates, and 8 of those sets are shared by more than one county; the largest covers 33 counties (the Olmsted County group).
