竞业禁止协议英文怎么说？

A non-compete clause or covenant not to compete (CNC), is a term used in contract law under which one party (usually an employee) agrees to not pursue a similar profession or trade in competition against another party (usually the employer).

所以竞业禁止协议，英文可以说成：

Non-compete Agreement
Non-competitive Agreement
Anti-competitive Agreement
Non-compete Clause
Covenant Not to Compete

个人觉得 Non-compete Agreement 是比较好些。
