Appeal dismissed: Employee on appointment cannot challenge dismissal without valid reason under Labor Code.

The Supreme Court dismissed the cassation appeal filed by Jarosław W. against a regional court ruling that rejected his claim to restore his position. The plaintiff argued that the dismissal was invalid due to a violation of social norms and procedural errors, but the court found no grounds for such claims. The decision rests on the principle that employees hired on a fixed-term appointment cannot effectively challenge a dismissal without a justified reason, as the employer retains the right to reorganize staff positions.
