A gag clause refers to a provision in a contract, typically an employment contract, that prohibits one party from disclosing certain information or speaking critically about another party. It restricts individuals from sharing or revealing specific details, opinions, or criticisms that could potentially harm the reputation or interests of the other party involved.

Example
In an employment contract, a gag clause may prevent an employee from discussing confidential company information with external parties or from making negative comments about the employer on social media platforms. This clause aims to protect sensitive information, maintain confidentiality, and preserve the organization's image or reputation.
