Must Article 7 of Directive 2003/88/EC and Article 31(2) of the Charter of Fundamental Rights of the European Union be interpreted as precluding national legislation or practice under which paid annual leave, which was requested by a worker and approved by the employer and which overlaps in time after the leave was approved with a government-ordered quarantine at home where a possible infection is suspected, may not be granted retroactively where the worker is not incapacitated for work on account of illness during that quarantine?
