Even if all the Democrats are on the run, the Wisconsin Senate is still doing business. Today, they passed a new rule that fines senators for unexcused absences and makes them pay the costs of finding and returning them to the capitol.
From the legislative summary:
Under this resolution, a senator who is absent without leave from two or more session days is subject to a penalty equal to $100 for each day that the senator is absent without leave. In addition, the senator must reimburse the senate for the actual costs incurred to compel his or her attendance. The penalties and costs are imposed by adopting a privileged resolution that identifies the senator who has been absent without leave.
The fines are taken from their per diem, valued at $88 per day when the senate is in session. But it's worth noting that the senators only make a base sallary of about $50,000 per year.
Many Wisconsin teachers make more than that.
