How to Include a Penalty Clause in an Employment Contract and Is It Enforceable?

Employment contracts may sometimes include penalty clauses. Under these provisions, employers may demand payments from employees if the employee takes certain actions. However, penalty clauses imposed unilaterally against the employee are generally considered invalid by the Supreme Court (Yargıtay).

New Developments Regarding Penalty Clauses

Employers occasionally insert penalty provisions when signing an employment contract with an employee. Notably, if an employee leaves work before a specified period, employers may claim amounts under these clauses that reach up to ten times the employee’s monthly salary. These provisions can lead to significant losses of rights for employees. The Labor Law does not contain a specific rule addressing penalty clauses. Under the Turkish Code of Obligations, however, penalty clauses imposed unilaterally to the detriment of the worker are deemed invalid. Supreme Court decisions have further clarified how these rules apply in practice.

When examining Supreme Court case law, the principle of interpreting provisions in favor of the employee is prominent. Clauses that operate solely to the detriment of the worker are declared invalid, while one-sided penalty clauses that favor the worker may be upheld. It is not enough for a penalty clause to mention both employer and employee; it must also avoid creating greater burdens on the worker than on the employer. Consequently, a penalty set against the worker cannot exceed the employer’s corresponding responsibility in scope or amount. In cases of bilateral penalty clauses, where an imbalance disproportionately disadvantages the worker, the clause is not always entirely voided; rather, the worker’s liability is limited so it does not exceed the employer’s assumed responsibility.

Penalty Clauses Against Employees Are Considered Invalid

Penalty provisions in fixed-term or indefinite employment contracts are valid when they are reciprocal. Therefore, penalty clauses included unilaterally and to the detriment of the worker are not accepted as valid. For a penalty clause tied to early termination to be enforceable, the employment agreement generally must be for a fixed term. According to Supreme Court rulings, if the contract is of indefinite duration, the employer cannot demand compensation under a penalty clause when the worker resigns. To enforce such a penalty, the employment relationship must have been established with a definite term. Accordingly, in indefinite-term contracts, penalty clauses can only be valid if they are not unilaterally disadvantageous to the employee.

Reciprocity Is Observed

The Supreme Court revisited the issue of penalty clauses in employment contracts following a specific case. In that case, a music teacher employed at a private school resigned after receiving an appointment from the Ministry of National Education. The private school owner sought compensation equal to ten months’ gross salary under the contract’s penalty clause. The trial court sided with the school, finding the teacher’s resignation during the academic year disrupted the school’s operations and ordered the teacher to pay the penalty. The written contract between the teacher and the school stated that if the contract was terminated before the agreed period for any reason, the teacher would owe ten times the minimum amount specified.

The local court relied on this contractual clause to rule in favor of the school. When the case reached the Supreme Court, however, the decision was overturned. The Supreme Court found that a clause stating “for any reason whatsoever” as a penalty was unenforceable because it placed an excessive and unilateral burden on the employee. The ruling emphasized that a one-sided penalty provision harming the worker cannot be applied. As a result, individuals should carefully review employment contracts for one-sided penalty clauses before signing.
