I tended to be in the camp of: I don’t care if we have PVDs as long as it makes my days easier and as long as I don’t have to have a helper in the car all day.
I can see now why the PVDs are bad long term for everyone: the company, drivers, part timers wanting to drive, the union and the PVDs themselves. They are a band-aid solution to a long term staffing problem.
Really and truly, if you are against having 22.4s in the contract, you should be against PVDs. It’s the same result just not negotiated.
