The Wisconsin 14

After more than a week of the shenanigans in Madison, WI, I'm still trying to figure why this new gang of 14 still have their jobs. Even though the WI state legislature passed a resolution to penalize these guys $100 per day plus any charged expenses, I think it's more simple than that. Wisconsin is an "at will" state and I don't understand why the employer of these AWOL state senator's, the citizens of WI, don't just relieve them of their duties. Just fire them and kick them to the curb. If I don't perform the duties of my job, my current employer can fire me without cause so I would like to know why these guys think they're special.
