Pursuant to the Working Environment Act (WEA) a part-time employee has priority to enlarge her post, before the employer can hire a new person for a vacant position. In administrative practices, it has long been assumed that a part-time employee also has priority to part of the vacant position. The part-time employee has thus been able to combine her existing part-time job with part of the vacant position to obtain a full-time position. In a recent ruling, the Supreme Court stated that this administrative practice and interpretation of the law is incorrect. The Court ruled that the part-time employee must claim priority to the entire vacant position to exercise her right to priority.
