Article 20
Mobile workers and offshore work 1. Articles 3, 4, 5 and 8 shall not apply to mobile workers. Member States shall, however, take the necessary measures to ensure that such mobile workers are entitled to adequate rest, except in the circumstances laid down in Article 17(3)(f) and (g). 2. Subject to compliance with the general principles relating to the protection of the safety and health of workers, and provided that there is consultation of representatives of the employer and employees concerned and efforts to encourage all relevant forms of social dialogue, including negotiation if the parties so wish, Member States may, for objective or technical reasons or reasons concerning the organisation of work, extend the reference period referred to in Article 16(b) to 12 months in respect of workers who mainly perform offshore work. 3. Not later than 1 August 2005 the Commission shall, after consulting the Member States and management and labour at European level, review the operation of the provisions with regard to offshore workers from a health and safety perspective with a view to presenting, if need be, the appropriate modifications.
