1. Where an employer is contemplating collective redundancies, he shall begin consultations with the workers' representatives in good time with a view to reaching an agreement.

2. These consultations shall, at least, cover ways and means of avoiding collective redundancies or reducing the number of workers affected, and of mitigating the consequences by recourse to accompanying social measures aimed, inter alia, at aid for redeploying or retraining workers made redundant.

Member States may provide that the workers' representatives may call on the services of experts in accordance with national legislation and/or practice.

3. To enable workers' representatives to make constructive proposals, the employers shall in good time during the course of the consultations:

(a) supply them with all relevant information and

(b) in any event notify them in writing of:

(i) the reasons for the projected redundancies;

(ii) the number and categories of workers to be made redundant;

(iii) the number and categories of workers normally employed;

(iv) the period over which the projected redundancies are to be effected;
