Zipper Clause Law and Legal Definition
A zipper clause is a clause in an employment agreement in which both parties waive the right to demand bargaining on any matter not dealt with in the contract, regardless of whether that matter was contemplated when the contract was negotiated or signed. A zipper clause in a written contract makes it clear that only the promises contained in that writing are part of the employment relationship.
The following is an example of a zipper clause:
"All matters within the scope of bargaining have been negotiated and agreed upon. The terms and conditions set forth in this Agreement represent the full and complete understanding and commitment between the District and the Association."
