1. There shall be no direct or indirect discrimination on grounds of sex in the public or private sectors, including public bodies, in relation to:

(a) conditions for access to employment, to self-employment or to occupation, including selection criteria and recruitment conditions, whatever the branch of activity and at all levels of the professional hierarchy, including promotion;

(b) access to all types and to all levels of vocational guidance, vocational training, advanced vocational training and retraining, including practical work experience;

(c) employment and working conditions, including dismissals, as well as pay as provided for in Article 141 of the Treaty;

(d) membership of, and involvement in, an organisation of workers or employers, or any organisation whose members carry on a particular profession, including the benefits provided for by such organisations.

2. Member States may provide, as regards access to employment including the training leading thereto, that a difference of treatment which is based on a characteristic related to sex shall not constitute discrimination where, by reason of the nature of the particular occupational activities concerned or of the context in which they are carried out, such a characteristic constitutes a genuine and determining occupational requirement, provided that its objective is legitimate and the requirement is proportionate.
