(b) may adopt, in the fields referred to in paragraph 1(a) to (i), by means of directives, minimum requirements for gradual implementation, having regard to the conditions and technical rules obtaining in each of the Member States. Such directives shall avoid imposing administrative, financial and legal constraints in a way which would hold back the creation and development of small and medium-sized undertakings.

The Council shall act in accordance with the procedure referred to in Article 251 after consulting the Economic and Social Committee and the Committee of the Regions, except in the fields referred to in paragraph 1(c), (d), (f) and (g) of this Article, where the Council shall act unanimously on a proposal from the Commission, after consulting the European Parliament and the said Committees. The Council, acting unanimously on a proposal from the Commission, after consulting the European Parliament, may decide to render the procedure referred to in Article 251 applicable to paragraph 1(d), (f) and (g) of this Article.

3. A Member State may entrust management and labour, at their joint request, with the implementation of directives adopted pursuant to paragraph 2.

In this case, it shall ensure that, no later than the date on which a directive must be transposed in accordance with Article 249, management and labour have introduced the necessary measures by agreement, the Member State concerned being required to take any necessary measure enabling it at any time to be in a position to guarantee the results imposed by that directive.

4. The provisions adopted pursuant to this Article:

- shall not affect the right of Member States to define the fundamental principles of their social security systems and must not significantly affect the financial equilibrium thereof,

- shall not prevent any Member State from maintaining or introducing more stringent protective measures compatible with this Treaty.

5. The provisions of this Article shall not apply to pay, the right of association, the right to strike or the right to impose lock-outs.
