An employment contract may state the amount of liquidated damages to be paid if the contract is breached. Upon a party's breach, the other party will recover this amount of damages whether actual damages are more or less than the liquidated amount.
If the agreed-upon liquidated damage amount is unreasonable, the Court will hold the liquidated damage clause to be void as a penalty. If the Court declares the clause to be void, the employee would have to prove the actual damages.
