Can previous work in a private company increase the jubilee award in the public sector?

The Supreme Court held that the exclusion of the period of employment with a private employer when determining the right to a jubilee award is unjustified. Such a provision in the internal regulations of the workplace is not binding. Employers creating or modifying remuneration regulations, the amount of which is shaped in relation to the length of service, should bear in mind that the jubilee award is a benefit of a remunerative and entitlement nature and is in the nature of a bonus due to the employee, not a reward. – Piotr Kuźniak comments for Rzeczpospolita.
