Generally not unilaterally. Changing a signed non-compete usually requires a new agreement and often new consideration — something of value given in exchange.
The law: In California, every contract that restrains anyone from engaging in a lawful profession, trade, or business is void to that extent, which voids employee non-compete clauses unless a statutory exception applies — Cal. Bus. & Prof. Code § 16600. Other states set their own rules.
A non-compete is a contract, and one side usually can’t rewrite a contract alone after both parties signed. To change it, your employer typically needs you to agree to a new version — and in many states, they must give you something of value ("consideration") in exchange for the new restrictions, not just your continued employment. Watch for updated handbooks or "acknowledgment" forms that quietly contain broader non-compete terms.
It depends on the state. Some accept continued employment as enough; others require separate consideration like a bonus or promotion for a mid-employment non-compete.
Enforceability varies dramatically by state — some (like California) void most non-competes entirely, while others enforce reasonable ones. The rules of your state control.
