male and female workers for equal work is applied. 2. For the purpose of this Article, "pay" means the ordinary basic or minimum wage or salary and any other consideration, whether in cash or in kind, which the worker receives directly or indirectly, in respect of his employment, from his employer. Equal pay without discrimination based on sex means: (a) that pay for the same work at piece rates shall be calculated on the basis of the same unit of measurement. (b) that pay for work at time rates shall be the same for the same job. 3. This Article shall not prevent any Member State from maintaining or adopting measures providing for specific advantages in order to make it easier for women to pursue a vocational activity or to prevent or compensate for disadvantages in their professional careers. ARTICLE 7 The Commission shall draw up a report each year on progress in achieving the objective of Article 1, including the demographic situation in the Community. It shall forward the report to the European Parliament, the Council and the Economic and Social Committee. The European Parliament may invite the Commission to draw up reports on particular problems concerning the social situation. DECLARATIONS 1. Declaration on Article 2(2) The eleven High Contracting Parties note that in the discussions on Article 2(2) of the Agreement it was agreed that the Community does not intend, in laying down minimum requirements for the protection of the safety and health of employees, to discriminate in a manner unjustified by the circumstances against employees in small and medium-sized undertakings. 2. Declaration on Article 4(2) The eleven High Contracting Parties declare that the first of the arrangements for application of the agreements between management and labour at Community level - referred to in Article 4(2) - will consist in developing, by collective bargaining according to the rules of each Member State, the content of the agreements, and that consequently this arrangement implies no obligation on the Member States to apply the agreements directly or to work out rules for their transposition, or any obligation to amend national legislation in force to facilitate their implementation.
