Got a Cease-and-Desist Over a Non-Compete in Michigan? Read This Before You Panic.

You left your job, started a new one, and a few weeks later a letter arrived from your former employer’s law firm. It says you’re violating your non-compete agreement. It demands that you “immediately cease and desist” working for your new employer. It threatens an injunction, damages, and attorney’s fees. Sometimes a copy goes to your new employer too.

I’ve seen a lot of these letters. The single most important thing I can tell you is this: a cease-and-desist letter is not a court order, it is not a lawsuit, and in most cases it is not even a serious threat of one. It’s a negotiating document. How you respond in the first week determines whether it stays that way.

What Michigan law actually requires of a non-compete

Michigan non-competes are governed by MCL 445.774a, part of the Michigan Antitrust Reform Act. The statute permits an employer to enforce a non-compete only if it protects the employer’s reasonable competitive business interests and is reasonable as to three things: its duration, its geographical area, and the type of employment or line of business it restricts.

Every word in that sentence is a battleground. “Reasonable competitive business interest” does not mean “we’d prefer you not compete with us.” Michigan courts have consistently held that an employer can’t use a non-compete simply to shield itself from ordinary competition. The interest has to be something more — protection of genuine trade secrets, confidential customer information, specialized training the employer invested in, or established customer goodwill that you personally carried. If you were a mid-level employee with no access to real confidential information, the employer’s “interest” argument is often weak from the start.

What makes a restraint over-broad

When I review a non-compete attached to a cease-and-desist letter, I’m scoring it on three axes:

• Duration. Michigan courts have generally treated six months to one year as the comfortable zone. Restrictions of two years or more draw real scrutiny, and the employer carries the burden of justifying them.
• Geography. The restricted territory should match where you actually worked and where the employer actually competes. A statewide or nationwide ban on a salesperson who covered three counties in metro Detroit is a red flag. So is a non-compete with no geographic limit at all.
• Scope of restricted activity. The narrowest enforceable version restricts you from doing the same job, for a direct competitor, in the same market. Agreements that bar you from working “in any capacity” for any company “in the industry” — so broad you couldn’t take a janitorial job at a competitor — are classically over-broad.

The more boxes the agreement fails, the more the cease-and-desist letter is bluffing.

The blue-pencil rule cuts both ways

Here’s the wrinkle that surprises most clients: in Michigan, an over-broad non-compete usually isn’t void. MCL 445.774a(1) expressly allows a court to limit an unreasonable agreement and enforce it as limited. Lawyers call this the blue-pencil rule, though Michigan’s version goes beyond crossing out words — courts can effectively rewrite the restriction down to a reasonable size.

That cuts both ways. For employers, it means they can draft aggressively, knowing the worst-case outcome is a trimmed agreement rather than a dead one. For you, it means “this agreement is ridiculous” is rarely a complete answer by itself — but it also means the realistic enforcement zone is much smaller than what the letter claims. A two-year, nationwide, any-capacity restriction might realistically be enforceable, if at all, as a one-year restriction on doing your old job in your old territory. The gap between what the letter demands and what a court would actually order is your negotiating room.

Why most cease-and-desist letters are leverage plays

Enforcing a non-compete is expensive. To actually stop you from working, the employer has to file suit, move for a preliminary injunction, and convince a judge — quickly, on real evidence — that it will suffer irreparable harm if you keep your new job. That requires proving the legitimate business interest, proving the agreement is reasonable, and usually proving you actually took or used something of value. Most employers don’t want to spend six figures finding out whether their template agreement holds up.

So they send a letter. The letter costs them a few hundred dollars and is designed to do the work a lawsuit would: scare you into quitting, or scare your new employer into firing you. A meaningful percentage of these disputes end after a well-crafted response letter from your lawyer explaining exactly why the agreement won’t hold and why interference with your new employment creates its own legal exposure. The employers who were bluffing go quiet. The ones who weren’t reveal themselves quickly, and then you negotiate from an informed position.

Where the law stands in 2026

Two developments come up in nearly every consultation, so let me give you the current status of both.

The FTC’s federal non-compete ban is dead. The FTC’s 2024 rule banning most non-competes was struck down by a federal court in Texas before it ever took effect. In September 2025, the FTC dropped its appeals, and the rule was formally removed from the Code of Federal Regulations in February 2026. There is no federal ban. The FTC has shifted to case-by-case enforcement against particularly abusive non-compete programs under its general unfair-competition authority — useful pressure in some industries, but nothing you can personally rely on. Your case will be decided under Michigan law.

Michigan has not banned non-competes — yet. House Bill 4040, introduced in 2025, would void nearly all employee non-competes in Michigan. As of this writing it has not passed; it remains in committee, and whether it becomes law is genuinely uncertain. Until it does, MCL 445.774a’s reasonableness standard controls. If the law changes, I’ll update this post.

What NOT to do

• Don’t quit your new job. Quitting is the outcome the letter was designed to produce, and it hands the employer a free win it might never have gotten from a judge. Until a court orders otherwise, you are allowed to keep working.
• Don’t reply yourself. Anything you write back — explanations, apologies, descriptions of your new role — becomes evidence. I’ve seen well-meaning self-drafted replies do more damage than the underlying facts ever could.
• Don’t sign anything. Sometimes the letter comes with a proposed “agreement” reaffirming or even expanding the restriction in exchange for the employer “not pursuing the matter.” Signing converts a shaky claim into a fresh, clean one.
• Don’t take, use, or keep anything from the old employer. If you still have files, customer lists, or devices, do not touch them — tell your lawyer. Actual misappropriation is what turns a leverage play into a real lawsuit.

What evidence to gather now

• The signed non-compete itself, plus your offer letter and any handbook or policy it references
• Anything showing when and how you signed it — was it presented on day one, or sprung on you mid-employment without anything new in return?
• A written description of your old job versus your new one: duties, territory, customers, products
• An honest inventory of what confidential information you actually had access to
• The cease-and-desist letter and its envelope or email metadata, plus anything sent to your new employer
• Names of former coworkers who left for competitors without being pursued — selective enforcement matters
