ANY voluntary behaviour could (and would, ultimately) become grounds for dismissal if this lot go on unchecked.

Anything they deem might someday affect your insurance payout would be fair game to prohibit in off hours. In fact, sitting around in a chair typing in a web forum in your private time and not exercising instead would be one. I suppose you will need to install a monitor on your CPU or your chair or body to see how long you spend sedentary during your off hours.

It is a short step from prohibiting behavior on the basis of healthcare costs...to requiring behavior on the basis of healthcare costs.

Ahhhh....you have found the key. It is a short step, from, "You must not..." to "You must..."

Nobody around here seems to get that.

If the employer pays 100% for your Health Care, everything included, than maybe they can set down some rules of healthy living so to speak.
If you are required to pay co-payments the deal is off, period! IMHO!
