Sort of a tragedy-of-the-commons bonus, then? Individual employees have the power to block bonuses, but not the power to ensure that they are not blocked, under this plan.
More likely a community policing of the commons. It’s not like Joe is secretly taking a package into the men’s room and smashing it. He’s doing it in full view and awareness of his co-workers in all likelihood. “Hey Joe, stop that, you’re killing our bonus!”
