Case C-514/20, Paid Leave

Do Article 31(2) of the Charter of Fundamental Rights of the European Union and Article 7 of Directive 2003/88/EC preclude a provision in a collective labour agreement which, for the purpose of calculating whether an employee is entitled to overtime pay and for how many hours, takes account only of the hours actually worked and not also of the hours during which the employee takes his paid minimum annual leave?
