(a) The board of education of any school district or the board of trustees of any community college may provide by resolution for deductions for specified purposes from the compensation paid to its employees. Any such resolution shall provide for written authorization from each employee, in specific terms as to the amount, subject to the provisions of subsection (b), purpose and disposition of any amounts so deducted. Deductions for taxes and other amounts required by law to be deducted from employees’ compensation shall not require written authorization of the employee.

(b) Written authorizations from employees for deductions from compensation for payments of professional association dues shall remain in effect until modified or revoked in writing by the professional association or the employee, or until the employee’s contract of employment is terminated. So long as the written authorization from an employee for deductions for professional association dues remains in effect and upon written notice of an increase in the amount of such dues being given to the board of education or the board of trustees and to all affected employees, the amount specified to be deducted in such written authorization may be increased by an amount deemed necessary by a professional association for a school year. In no event shall the amount of deductions from compensation for payments of professional association dues be increased more than one time in each school year without specific written authorization from the employee for such increase.
