In the United States, an employer generally cannot take away or refuse to pay for hours an employee has already worked. Federal and state wage laws require employers to pay for all time worked at the agreed rate. Reducing or withholding earned wages is usually illegal, even if the employer is unhappy with performance or scheduling issues.

If hours were recorded incorrectly due to a genuine or timekeeping error, an employer may correct the mistake, but only to reflect the actual hours worked. They cannot retroactively remove valid work hours. Any adjustment must be accurate, documented, and compliant with minimum wage and overtime laws.

Employers may reduce future scheduled hours as a form of discipline or cost control, but they cannot erase hours already worked. Even if an employee violated a or worked without approval, the employer must still pay for that time, though separate disciplinary action may be taken. This ensures compliance with labor laws while maintaining accountability.
