Article 12 Protection from dismissal and burden of proof
1. Member States shall take the necessary measures to prohibit the dismissal and all preparations for the dismissal of workers, on the grounds that they have applied for, or have taken, leave provided for in Articles 4, 5 and 6, or have exercised the right to request flexible working arrangements referred to in Article 9.
2. Workers who consider that they have been dismissed on the grounds that they have applied for, or have taken, leave provided for in Articles 4, 5 and 6, or have exercised the right to request flexible working arrangements as referred to in Article 9, may request the employer to provide duly substantiated reasons for their dismissal. With respect to the dismissal of a worker who has applied for, or has taken, leave provided for in Article 4, 5 or 6, the employer shall provide reasons for the dismissal in writing.
3. Member States shall take the measures necessary to ensure that where workers who consider that they have been dismissed on the grounds that they have applied for, or have taken, leave provided for in Articles 4, 5 and 6 establish, before a court or other competent authority, facts capable of giving rise to a presumption that they have been dismissed on such grounds, it shall be for the employer to prove that the dismissal was based on other grounds.
