Unjustified economic wage increase before employer change justifies employer's termination of employment terms.

The Supreme Court dismissed the cassation appeal filed by Urszula M. seeking reinstatement to her previous employment terms. The court found that the employer's reduction of her salary was justified by an unjustified economic wage increase from her former employer and the need to align pay with her unchanged duties. Consequently, the court ruled that the employer acted within legal bounds and did not violate social coexistence principles.
