PT Car Washer
We use PT and 22.3 air drivers and pay them top FT driver rate.Not sure what local OP is in but here's the applicable language for my local regarding their pay
4.02 The Utility Driver rate of pay will be the start rate of a package driver pursuant to Article 41 Section 2(c) of the NMUPSA or the regular rate of the employee, whichever is greater.
In practice up here these are usually (or always from what I've seen) part time inside employees who are trained and qualified to drive and get used as all purpose cover drivers with no restrictions aside from DOT regulations. They do progress as whatever their "regular" job is so they could technically get a raise beyond starting driver pay if they happen to have a better regular job than a basic part time classification or if they receive an MRA big enough but I haven't heard of either happening.
