My point is that NOBODY should wad up if someone wants to do something, during work, that they don't advocate for.
I've read here, more than once, where drivers come in early to sort their shelves. They are making an investment in their day IMO. They can make their truck grab and go instead of hunt and peck. How much time is saved when your truck is perfectly sorted compared to the average sorting that's generally done. Maybe an hour? Maybe these drivers want to get home to their families an hour early and invest their own time in the effort to do so.
If this is decision I made, as a driver, and some union militant came to me and said something about MY decision there would be a BIG problem.
