Section 4004 - Employee organization as exclusive representative(a) The employee organization designated or selected for the purpose of collective bargaining by the majority of the employees in an appropriate collective bargaining unit shall be the exclusive representative of all the employees in the unit for such purpose and shall have the duty to represent all unit employees without discrimination. Where an exclusive representative has been certified, a public school employer shall not bargain in regard to matters covered by this chapter with any employee, group of employees or other employee organization.(b) Nothing contained in this section shall prevent employees individually, or as a group, from presenting complaints to a public school employer and from having such complaints adjusted without the intervention of the exclusive representative for the bargaining unit of which they are a part, as long as the representative is given an opportunity to be present at such adjustment and to make its view known, and as long as the adjustment is not inconsistent with the terms of an agreement between the public school employer and the exclusive representative which is then in effect. The right of the exclusive representative shall not apply where the complaint involves matters of personal, embarrassing and confidential nature, and the complainant specifically requests, in writing, that the exclusive representative not be present.(c) Any employee organization which has been certified as an exclusive representative shall have the right to have its dues deducted and collected by the employer from the salaries of those employees, within the bargaining unit, who authorize, in writing, the deduction of said dues. Such authorization is revocable at the employee's written request, provided that said revocation shall not be effective until the next ensuing August 31 after the employer's receipt of the written notice. Said deductions shall commence upon the exclusive representative's written request to the employer. Such right to deduction shall be in force for so long as the employee organization remains the exclusive bargaining representative for the employees in the unit. The public school employer is expressly prohibited from any involvement in the collection of fines, penalties or special assessments levied on members by the exclusive representative.14 Del.
