The aim of this article is to discuss the impact of the amend­ment to the Labour Code concerning the inclusion of other periods of professional activity in the period of employment on the legal situation of public sector employees, in particu­lar employees of provincial administrative courts, common courts and public prosecutor’s offices. The main research question is to determine the effects of the amendment in question and the possibility for employees to acquire finan­cial entitlements retroactively, as well as the possibility of claiming their payment. The article also includes an analysis of systemic inconsistencies arising from various professional regulations and a proposal to resolve these inconsistencies.
