Labor contract amendment requires written form under penalty of invalidity; oral changes are void.
Legislator summary
AI generatedThe Supreme Court dismissed the cassation appeal filed by an employee against a labor court judgment. The court found that the employer's board resolution did not constitute a valid oral modification of the employment contract because the contract explicitly required written amendments under penalty of invalidity. Consequently, the employee's claim for additional wages and severance based on alleged oral changes was rejected as unsupported by the facts.
