Fixed-term employment contract terminated by mutual agreement via conduct is valid and not contrary to social norms.

The Supreme Court dismissed the plaintiff's cassation appeal regarding a claim for severance pay after his fixed-term employment contract ended. The court found that the contract was validly terminated by mutual agreement through conduct, based on the employer's objection to the plaintiff's poor work performance and lack of qualifications. Consequently, the court ruled that such a termination was not contrary to social norms and the lower courts correctly applied the law.
