An employee facing enforcement has more arguments than the agreement suggests.

Validity. No protectable interest; overbroad duration, geography or activity; lack of consideration where independent consideration is required; and statutory prohibitions.

Choice of law and forum. Where the employee resides in a state hostile to non-competes, its public policy may displace a contractual choice, and several states void such clauses by statute for resident employees. Filing first at home is a recognized and effective response.

Prior material breach by the employer — unpaid compensation, a change in role, or termination without cause where the agreement conditions enforcement.

Termination without cause. Several states and many agreements make a covenant unenforceable where the employer terminated the relationship.

Changed circumstances. A covenant signed for a different role, years earlier, where the employee’s function has changed.

No breach. The new role does not fall within the restricted activity, or the customers are outside the restricted set.

Conduct that destroys the defense. Taking documents, deleting files, lying about the new employer, and soliciting before departure. These convert a defensible position into an indefensible one, and they are what the forensic evidence shows.
