In March 2019, Royal Decree-Law 6/2019, on urgent measures guaranteeing equal treatment of men and women and equal opportunities in employment and occupation (RDL 6/2019), amended article 34.8 of the Workers Statute (WS), significantly rewording the right to adjust working hours. RDL 6/2019 defined it as a right of “autonomous” exercise, although subject to collective bargaining or individual worker-employer negotiations.
