A single reader's working-out of how post-employment restrictions get read, argued and abandoned, written down because the answers sit in scattered statutes and one paid consultation.
Two engineers sign the same template on the same day, one in Sacramento and one in Charlotte, and eighteen months later only one of them is stuck. Nothing about the language changed. What changed is the body of law reading it, and state law on post-employment restraints varies more than almost any other term in an ordinary employment contract. That variation is not a technicality you can safely leave to counsel later. It determines which sentence in your agreement matters most, and in a surprising number of cases the decisive sentence is not the restriction at all.
Start with the state the contract picked, not the one you live in
Most employees read the non-compete paragraph first, measure the months and the mileage, and form a view. That is the wrong order. Find the governing law clause, usually buried near the end beside notices and severability, and find the forum clause that names where suit must be filed. Those two sentences decide which rulebook applies to everything above them. A twelve-month nationwide restraint drafted under Delaware or Florida law is a different instrument from the identical words read under California or Minnesota law, and the gap between those readings is often the whole case.
Bans, thresholds, and the numbers that move every session
A handful of states refuse to enforce employee non-competes almost entirely, treating them as void rather than merely narrowing them. A larger group enforces them only above an income floor, so that a worker earning below a set annual figure cannot be bound at all, and those floors are frequently indexed and revised. Others add procedural conditions: advance notice before signing, a copy delivered with the offer, separate consideration for a mid-employment agreement. The Federal Trade Commission has taken up non-competes as a competition question at the national level, which is why the state-by-state picture keeps moving. Check the current figure for your state and your signing date, not the figure someone quoted you two years ago.
Blue pencil, reformation, or the whole thing falls
When a court decides a restraint reaches too far, what it does next varies in a way that changes your exposure enormously. Strict blue-pencil states will strike offending words if the clause can be cut cleanly, but will not rewrite it, so a single indivisible sentence covering the entire United States may fail outright. Reformation states go further and redraft the term to something reasonable, which means an overbroad clause is not a defense so much as an invitation to a narrower one. A third approach rejects the covenant wholesale on the theory that employers should not be rewarded for overreaching. Knowing which camp your governing law sits in tells you whether overbreadth is your best argument or your worst.
Why the choice-of-law clause is usually the real fight
Employers with multistate workforces tend to standardize on friendly law, and employees tend to assume that choice is binding. Often it is not. Several protective states have statutes voiding any provision that deprives a resident employee of local law or a local forum, and courts in those states will apply their own public policy over a contractual designation when the employee lived and worked there. The result is a race: the employer files first in its chosen forum seeking an injunction, the employee files first at home seeking a declaration that the covenant is void, and whoever moves first frequently sets the law that governs. That timing question is worth a phone call the week you resign, not the month after.
What a careful reader writes down before the consultation
Assemble the signed agreement with every amendment, the offer letter, any equity or bonus document that repeats the restraint in different words, and the dates and addresses that establish where you actually worked. Note your compensation at signing and at departure, because thresholds are measured differently in different statutes. Note whether you signed before starting or years into the job, and what you received in exchange. Then flag the governing law state, the forum state, your residence state, and the state of the client or territory you are accused of touching. Four states, four possible answers, and an attorney can triage that list in one sitting if you hand it over already sorted.
The restriction itself is the part everyone argues about in the parking lot. The part that decides the outcome is quieter, sits lower on the page, and is usually settled before anyone reaches the mileage radius.
