Employer's change of terms constitutes breach of job security only if it reveals intent to terminate employment definitively.

The Supreme Court quashed the appellate court's dismissal of the employee's claim regarding the employer's breach of job security guarantees. The court found that the employer's proposal of new working conditions and salary did not constitute a breach because the employer's true intent was not to continue the employment relationship but to definitively end it. Consequently, the case was remanded to the Poznań Court of Appeal for a new decision on the merits and costs.
