Can my employer change my pay without telling me?

The short answer: they can usually lower it going forward. They can almost never lower it for work you have already finished.

You open your pay stub and the number is wrong. Not a rounding error — the rate itself has changed, and nobody told you. What are your rights?

The answer splits cleanly in two, and the split is the most important thing on this page.

The line that cannot be crossed: retroactive cuts

An employer cannot reduce your pay for work you have already performed. This is close to absolute, and it holds in every state.

If you worked last week under an agreed rate of $25 an hour, you are owed $25 an hour for those hours. Your employer cannot decide after the fact to pay you $22. California's Division of Labor Standards Enforcement puts it plainly: wage decreases can only be made prospectively, never retroactively for work already performed under a specified rate.

Pay for completed work is an earned wage. Taking it back is wage theft, and it is actionable.

Going forward is a different story

Most American employment is at will. Absent a contract or a union agreement, your employer can generally change the terms of your job — including your pay rate — for future work, and you can generally quit if you don't like it. That's the deal, and it's harsher than most people realize.

Three hard limits apply even so:

• Minimum wage. Your new rate cannot fall below the federal minimum ($7.25) or your state or city minimum, whichever is highest.
• Overtime. If you're non-exempt, you still get time-and-a-half past 40 hours — calculated on the new rate.
• It cannot be retaliation or discrimination. A pay cut because you reported harassment, filed a wage claim, took protected leave, or because of your race, sex, religion, age or disability is illegal, full stop.

Do they have to tell you first?

Here is the part that surprises people: there is no federal law requiring an employer to give you notice of a pay change. None.

But a majority of states, plus D.C. and some localities, do require it — and the rules vary a great deal:

That table is a sample, not a complete list, and these rules change. Look up your own state labor department — it takes two minutes and it is the difference between "unfair" and "illegal."

The through-line even in states with no notice law: you cannot be paid the new, lower rate for hours you worked before you knew about it. If your employer cut your rate on Monday and told you on Friday, Monday through Thursday are owed at the old rate.

The contract exception

All of the above assumes at-will employment. If you have any of the following, the analysis changes completely and in your favor:

• An employment contract specifying your rate — they're bound by it.
• A collective bargaining agreement — pay is negotiated, and unilateral changes are typically a violation. Talk to your rep.
• A written offer letter or wage agreement — not always a binding contract, but it's evidence of what was agreed, and ambiguity is often construed against the employer who wrote it.

The exempt-status trap

A detail that catches employers out, and is worth knowing if it's you.

If you're a salaried exempt employee and your pay is cut below the applicable exempt threshold — $684 a week federally, and considerably higher in states like California and Washington — you may lose exempt status entirely. Which means you become non-exempt. Which means you're now owed overtime for every hour past 40.

Docking a salaried employee's pay based on the quantity or quality of their work can also break the "salary basis" test and destroy the exemption. The full test is here.

What to do, in order

1. Get it in writing. Email your manager or HR: "Confirming my rate changed from $X to $Y effective [date]." A written record is what makes a claim provable.
2. Check the dates. Compare when the new rate started against when you were told. Any hours in that gap should be paid at the old rate.
3. Check your state's notice law. Your state labor department publishes it.
4. Check the floor. New rate below minimum wage? Illegal. Salary cut below the exempt threshold? You may now be owed overtime.
5. Ask your coworkers. If everyone got cut, it's a business decision. If only you did, ask yourself what happened just before — and whether it was protected activity.
6. File if it isn't fixed. Your state labor commissioner and the U.S. Department of Labor's Wage and Hour Division both take wage complaints at no cost. Retaliating against you for filing is itself illegal.

And practically: recalculate what the new rate actually means before you decide how to respond. A $2 cut sounds survivable until you see it's $4,160 a year.

General information, not legal advice. Wage and notice laws vary significantly by state and change often. For your situation, consult your state labor agency or a licensed employment attorney.
