About Back Pay
Back pay is compensation for wages you earned but didn't receive. This can happen due to unpaid regular hours, unpaid overtime, minimum wage violations, late final pay, or misclassification. In addition to the unpaid wages, many jurisdictions allow interest, penalties, or liquidated damages that can significantly increase what you're owed.
Waiting Time Penalties
Some states require employers to pay additional penalties (often 30 days of wages) for late final pay.
Liquidated Damages
Many states allow liquidated damages equal to unpaid wages, effectively doubling what you're owed.
Statutory Interest
Some states have statutory interest rates (e.g., California 10%, Massachusetts 12%) on unpaid wages.
