For a variety of reasons, an employer might want to decrease your wage, salary, or other compensation. An employer can legally reduce your pay, but they must first inform you in writing at least 7 days before any decrease.
Keep in mind, however, that if a collective bargaining agreement, contract, law, or regulation applies to your pay arrangement, then your employer must comply with any terms regarding pay or notice contained in the law, regulation, or agreement.
By following these requirements, employers can legally reduce your pay for work you do in the future, but they can’t decrease your pay for work you’ve already done. They can’t require you to rebate, refund, or return any wage, salary, or other compensation they have paid you. Only in certain circumstances can employers deduct wages from your paycheck before paying you.
