Supreme Court dismissed appeal; work performance risk clauses cannot shift labor law obligations to employees.

The Supreme Court dismissed the cassation appeal filed by an employee against a labor contract clause limiting weekly hours to 39, contingent on achieving 100% productivity targets. The court found that the employer attempted to transfer the risk of project delays and performance fluctuations to the worker, violating the principle that work tasks must be achievable within normal working time. Consequently, the clause was declared invalid under Article 18 of the Labor Code, and the judgment was upheld.
