When an employer has granted paid leave under the provisions of paragraphs (5) through (7) of Article 39 of the Act, the employer must prepare a document which makes clear, for each worker, the time, the number of days and the base date (including the first base date and the second base date) (referred to as the "annual paid leave management register" in Article 55-2 and paragraph (3) of Article 56), and must preserve it during the period in which that paid leave was granted and for five years after the expiration of that period.
