Supreme Court dismissed appeal; payment of wage increase negates need for formal declaration of will.

The Supreme Court dismissed the union's cassation appeal against a labor court ruling that rejected claims for unpaid wage increases. The court found that although a written declaration of acceptance for the 2002 wage hike was missing, the employer had already paid the increased amount, rendering a formal declaration unnecessary. Consequently, the court held that the procedural requirement for a written statement was satisfied by the actual performance of the wage increase.
