In California, an employer generally cannot change your pay without notice. For hourly (non-exempt) employees, Labor Code Section 2810.5 requires written notice of any change to your pay rate, and the new rate can only apply going forward. A pay cut can never reach back to hours you have already worked, regardless of who you are or how you are paid.
Pay You’ve Already Earned Is Locked In
Once you complete a shift or finish a task, the rate you were promised for that work becomes a debt your employer owes you. California defines “wages” broadly to cover everything you earn for labor, whether by the hour, by commission, by piece rate, or any other method.1California Legislative Information. California Code Labor Code 200 – Payment of Wages A pay cut announced Wednesday cannot rewrite what you earned Monday.
Labor Code Section 223 backs this up by making it illegal for an employer to secretly pay less than the wage set by statute or contract.2California Legislative Information. California Code Labor Code 223 A retroactive reduction is treated as an illegal withholding of earned wages, and you can recover the full amount.
Written Notice Before Any Future Pay Change
Your employer can lower your pay going forward, but only if you know about it before you do the work. For non-exempt employees, Labor Code Section 2810.5 requires a written notice any time your pay rate changes. The notice has to arrive within seven calendar days of the change and include your new rate, the basis for how you are paid (hourly, salary, piece rate, and so on), and any applicable overtime rates.3California Legislative Information. California Code Labor Code 2810.5
There are two ways your employer can satisfy that requirement without handing you a separate notice. The change can appear on a timely wage statement (your pay stub) under Labor Code Section 226, or the notice can come through another writing already required by law within the seven-day window.3California Legislative Information. California Code Labor Code 2810.5 Either way, the principle is the same: you must know the new rate before performing work at that rate. A pay cut that turns up as a surprise on your check, applied to hours you already worked at the old rate, is not legal.
Salaried Exempt Employees Follow a Different Path
Section 2810.5 does not cover employees who are exempt from overtime.3California Legislative Information. California Code Labor Code 2810.5 If you are a salaried exempt employee, your employer has no statutory duty to give you a written wage-change notice. You still have protections, though, they just come from a different place.
Under federal law, exempt employees must be paid on a “salary basis,” meaning a predetermined amount each pay period that does not fluctuate based on the quality or quantity of work. Docking your salary because business slowed or there was not enough work to fill your week can destroy the exemption and make you eligible for overtime on any hours over eight in a day or 40 in a week.4U.S. Department of Labor. Fact Sheet 17G – Salary Basis Requirement and the Part 541 Exemptions Under the Fair Labor Standards Act An employer can reduce an exempt salary prospectively for legitimate reasons, but the new salary must still meet the federal minimum of $684 per week ($35,568 per year) to keep the exemption intact.5U.S. Department of Labor. Earnings Thresholds for the Executive, Administrative, and Professional Exemptions Reducing a salary below that floor effectively reclassifies the position.
Commissions and Bonuses Have Their Own Rules
If any part of your pay comes from commissions, California requires the commission plan to be in writing and signed by both sides.6California Legislative Information. California Code Labor Code 2751 – Employment Contracts Involving Commissions Changes to the structure apply only to sales that happen after you receive written notice of the new terms. A deal you closed last Thursday under one plan cannot be repriced under a less favorable plan later.
Bonuses split into two categories. Non-discretionary bonuses, where you know in advance what you need to do to earn them, are wages. Your employer cannot change the formula or take the bonus away after you have met the conditions. Discretionary bonuses, where the employer decides on the fly whether to pay and how much, are not earned wages and can be adjusted or dropped without the same limits.
No Pay Cut Can Bring You Below Minimum Wage
Notice or no notice, no reduction can drop your rate below the applicable minimum wage. California’s statewide minimum is $16.90 per hour as of January 1, 2026.7Department of Industrial Relations. Minimum Wage Many cities and counties set higher minimums, so the floor that applies to you depends on where you work, not just where the company is headquartered. If a pay change effectively pays you less than the applicable minimum for any hours worked, you can recover the unpaid wages plus liquidated damages in an equal amount.8California Legislative Information. California Code Labor Code 1194.2 The employer can avoid liquidated damages only by proving the violation was made in good faith with reasonable grounds for believing the pay was lawful.
What to Do If Your Employer Cut Your Pay Improperly
If your employer reduced your pay retroactively, or lowered it going forward without proper written notice, you can file a wage claim with the Division of Labor Standards Enforcement (DLSE), the arm of California’s Department of Industrial Relations that handles unpaid-wage disputes. Before filing, pull together your pay stubs, time records, employment contract or offer letter, and any written communications about the pay change.9Department of Industrial Relations. Instructions for Filing a Wage Claim
If the DLSE finds your employer withheld wages, the exposure goes beyond the wages themselves. California adds interest at 10 percent per year on unpaid wages, running from the date each payment was originally due.10California Legislative Information. California Code Labor Code 218.611California Legislative Information. California Civil Code 3289
Waiting Time Penalties If You’ve Left the Job
The penalties climb further if you have already separated from the employer and the wages still haven’t been paid. Labor Code Section 203 imposes a penalty equal to your daily rate for every day the wages remain unpaid, up to 30 calendar days including weekends and holidays.12Department of Industrial Relations. Waiting Time Penalties For a worker earning $200 a day, that is up to $6,000 in penalties on top of the unpaid wages and interest.
You Are Protected From Retaliation for Complaining
Raising a concern about a pay reduction or filing a wage claim is protected activity. Labor Code Section 98.6 prohibits your employer from firing, demoting, suspending, or otherwise retaliating against you for making a written or oral complaint about unpaid wages, or for filing a claim with the DLSE.13California Legislative Information. California Code Labor Code 98.6
The law adds a strong presumption on your side. If your employer takes adverse action against you within 90 days of your protected activity, retaliation is presumed, and the employer has to prove the action was taken for a legitimate, unrelated reason.13California Legislative Information. California Code Labor Code 98.6 If the employer cannot overcome the presumption, you are entitled to reinstatement, reimbursement for lost wages and benefits, and a civil penalty of up to $10,000 per violation. That 90-day window is worth knowing before you decide whether to speak up.
When a Pay Cut Is Big Enough to Quit and Still Collect Unemployment
A large enough pay cut can give you good cause to leave the job without losing unemployment benefits. Under California’s unemployment regulations, a reduction of 20 percent or more is generally considered a substantial reduction that establishes good cause for quitting.14Cornell Law Institute. California Code of Regulations Title 22, Section 1256-22 – Voluntary Leaving – Good Cause “Pay” for this purpose covers your base wage, shift differentials, guaranteed overtime, and fringe benefits like vacation pay and insurance.
Below 20 percent, you may still qualify if other factors made the working conditions unreasonable, such as a longer commute, loss of advancement opportunities, or reduced hours combined with the pay cut. The test is whether a reasonable person who genuinely wanted to keep working would have left under the same circumstances.14Cornell Law Institute.
