It uses about 1 KWH per charge, for me at home that's about $.10.
I appreciate all the suggestions, some may help and some may not. Unfortunately the ones that sound like they would work in a normal situation will not work in this case, at least not on the local level.
While you would think they would see the positives in this (employee morale, fitness, green image, lower health insurance cost) and maybe use to their advantage, they are TOTALLY blind to all of that.
As 350htrr posted above it will probably only be solved if their hand if forced somehow.
We do have a few things in the works that I don't want to disclose publicly at this point.

This is charging my E+ with two batteries. First pic is KWH second is total time on charger like this hours:minutes.
