Supreme Court dismissed appeal; employer may document employee non-performance; records must be in personnel files.

The Supreme Court dismissed the plaintiff's cassation appeal against a labor court decision ordering the destruction of employer records. The plaintiff sought to destroy confidential notes documenting his failure to perform duties, arguing they violated data protection laws. The court ruled that while such storage in a separate segregator was procedurally flawed, the employer retains the right to document non-performance, and the plaintiff could only demand proper inclusion in official personnel files.
