Wis. Admin. Code Department of Administration Adm 30.10
The secretary may, as a matter of administrative convenience, determine that there will be only one payroll deduction for charitable contributions from each employee's paycheck, and that the total amounts deducted from state employees' salaries for charitable purposes, either on a state-wide or area-wide basis, shall be paid to one umbrella organization for distribution. If this procedure is followed, the total charitable contributions shall be sent to the umbrella organization designated by all umbrella organizations as their agent for this purpose, and the actual distribution to each umbrella organization or charitable organization shall be the responsibility of the designated umbrella organization.
