“Each Member State shall ensure that the principle of equal pay for male and female workers for equal work or work of equal value is applied.”
“(1) If the terms of a contract under which a woman is employed at an establishment in Great Britain do not include (directly or by reference to a collective agreement or otherwise) an equality clause they shall be deemed to include one. (2) An equality clause is a provision which relates to terms (whether concerned with pay or not) of a contract under which a woman is employed (the “woman’s contract”), and has the effect that – (a) where the woman is employed on like work with a man in the same employment – (i) if (apart from the equality clause) any term of the woman’s contract is or becomes less favourable to the woman than a term of a similar kind in the contract under which that man is employed, that term of the woman’s contract shall be treated as so modified as not to be less favourable, and (ii) if (apart from the equality clause) at any time the woman’s contract does not include a term corresponding to a term benefiting that man included in the contract under which he is employed, the woman’s contract shall be treated as including such a term; (b) where the woman is employed on work rated as equivalent with that of a man in the same employment – (i) if (apart from the equality clause) any term of the woman’s contract determined by the rating of the work is or becomes less favourable to the woman than a term of a similar kind in the contract under which that man is employed, that term of the woman’s contract shall be treated as so modified as not to be less favourable, and (ii) if (apart from the equality clause) at any time the woman’s contract does not include a term corresponding to a term benefiting that man included in the contract under which he is employed and determined by the rating of the work, the woman’s contract shall be treated as including such a term; (c) where a woman is employed on work which, not being work in relation to which paragraph (a) or (b) above applies, is, in terms of the demands made on her (for instance under such headings as effort, skill and decision), of equal value to that of a man in the same employment – (i) if (apart from the equality clause) any term of the woman’s contract is or becomes less favourable to the woman than a term of a similar kind in the contract under which that man is employed, that term of the woman’s contract shall be treated as so modified as not to be less favourable, and (ii) if (apart from the equality clause) at any time the woman’s contract does not include a term corresponding to a term benefiting that man included in the contract under which he is employed, the woman’s contract shall be treated as including such a term. (3) An equality clause…… shall not operate in relation to a variation between the woman’s contract and the man’s contract if the employer proves that the variation is genuinely due to a material factor which is not the difference of sex and that factor – (a) in the case of an equality clause falling within subsection (2)(a) or (b) above, must be a material difference between the woman’s case and the man’s; and (b) in the case of an equality clause falling within subsection (2)(c) above, may be such a material difference (4) A woman is to be regarded as employed on like work with men if, but only if, her work and theirs is of the same or a broadly similar nature, and the differences (if any) between the things she does and the things they do are not of practical importance in relation to terms and conditions of employment; and accordingly in comparing her work with theirs regard shall be had to the frequency or otherwise with which any such differences occur in practice as well as to the nature and extent of the differences. (5) A woman is to be regarded as employed on work rated as equivalent with that of any men if, but only if, her job and their job have been given an equal value in terms of the demand made on a worker under various headings (for instance effort, skill, decision), on a study undertaken with a view to evaluating in those terms the jobs to be done by all or any of the employees in an undertaking or group of undertakings, or would have been given an equal value but for the evaluation being made on a system setting different values for men and women on the same demand under any heading.” (a) where the woman is employed on like work with a man in the same employment – (i) if (apart from the equality clause) any term of the woman’s contract is or becomes less favourable to the woman than a term of a similar kind in the contract under which that man is employed, that term of the woman’s contract shall be treated as so modified as not to be less favourable, and (ii) if (apart from the equality clause) at any time the woman’s contract does not include a term corresponding to a term benefiting that man included in the contract under which he is employed, the woman’s contract shall be treated as including such a term; (b) where the woman is employed on work rated as equivalent with that of a man in the same employment – (i) if (apart from the equality clause) any term of the woman’s contract determined by the rating of the work is or becomes less favourable to the woman than a term of a similar kind in the contract under which that man is employed, that term of the woman’s contract shall be treated as so modified as not to be less favourable, and (ii) if (apart from the equality clause) at any time the woman’s contract does not include a term corresponding to a term benefiting that man included in the contract under which he is employed and determined by the rating of the work, the woman’s contract shall be treated as including such a term; (c) where a woman is employed on work which, not being work in relation to which paragraph (a) or (b) above applies, is, in terms of the demands made on her (for instance under such headings as effort, skill and decision), of equal value to that of a man in the same employment – (i) if (apart from the equality clause) any term of the woman’s contract is or becomes less favourable to the woman than a term of a similar kind in the contract under which that man is employed, that term of the woman’s contract shall be treated as so modified as not to be less favourable, and (ii) if (apart from the equality clause) at any time the woman’s contract does not include a term corresponding to a term benefiting that man included in the contract under which he is employed, the woman’s contract shall be treated as including such a term. (3) An equality clause…… shall not operate in relation to a variation between the woman’s contract and the man’s contract if the employer proves that the variation is genuinely due to a material factor which is not the difference of sex and that factor – (a) in the case of an equality clause falling within subsection (2)(a) or (b) above, must be a material difference between the woman’s case and the man’s; and (b) in the case of an equality clause falling within subsection (2)(c) above, may be such a material difference (4) A woman is to be regarded as employed on like work with men if, but only if, her work and theirs is of the same or a broadly similar nature, and the differences (if any) between the things she does and the things they do are not of practical importance in relation to terms and conditions of employment; and accordingly in comparing her work with theirs regard shall be had to the frequency or otherwise with which any such differences occur in practice as well as to the nature and extent of the differences. (5) A woman is to be regarded as employed on work rated as equivalent with that of any men if, but only if, her job and their job have been given an equal value in terms of the demand made on a worker under various headings (for instance effort, skill, decision), on a study undertaken with a view to evaluating in those terms the jobs to be done by all or any of the employees in an undertaking or group of undertakings, or would have been given an equal value but for the evaluation being made on a system setting different values for men and women on the same demand under any heading.”
“5….It is noteworthy that, as the United Kingdom concedes, British legislation does not permit the introduction of a job classification system without the employer’s consent. Workers in the United Kingdom are therefore unable to have their work rated as being of equal value with comparable work if their employer refuses to introduce a classification system. 6.The United Kingdom attempts to justify that state of affairs by pointing out that Article 1 of the Directive says nothing about the right of an employee to insist on having pay determined by a job classification system. On that basis it concludes that the worker may not insist on a comparative evaluation of different work by the job classification method, the introduction of which is at the employer’s discretion.”
“8. Bord Telecom Eireann contends that the principle does not apply in the situation where a lower wage is paid for work of higher value. In support of its view it maintains that the term “equal work” in Article 119 of the EEC Treaty cannot be understood as embracing unequal work and the effect of a contrary interpretation would be that equal pay would have to be paid for work of different value. 9. It is true that Article 119 expressly requires the application of the principle of equal pay for men and women solely in the case of equal work or, according to a consistent line of decisions of the Court, in the case of work of equal value, and not in the case of work of unequal value. Nevertheless, if that principle forbids workers of one sex engaged in work of equal value to that of workers of the opposite sex to be paid a lower wage than the latter on grounds of sex, it a fortiori prohibits such a difference in pay where the lower-paid category of workers is engaged in work of higher value. 10. To adopt a contrary interpretation would be tantamount to rendering the principle of equal pay ineffective and nugatory. As the Irish government rightly emphasised, in that case an employer would easily be able to circumvent the principle by assigning additional or more onerous duties to workers of a particular sex, who could then be paid a lower wage.”
“Article 119 of the EEC Treaty must be interpreted as covering the case where a worker who relies on that provision to obtain equal pay within the meaning thereof is engaged on work of higher value than that of the person with whom a comparison is to be made.”
“The principle of equal pay for men and women outlined in Article 119 of the Treaty of Rome is to outlaw discriminatory practices which primarily disadvantage women.The Equal Pay Act 1970 domestic legislation treated as implementing the Council Directive regarding equal pay. On any purposive construction of the Act, the fact that a promoted woman undertakes more duties than her male predecessor cannot result in a conclusion that the two are not undertaking like work in order to justify her being paid less.”
“There is no justification for distinguishing between work rated as equivalent and equal value claims since they have to be read together as the implementation of the Article 141 duty to provide equal pay for work of equal value. This in our judgment is plainly so, since an equal value claim is not open to a claimant whose work has been rated as equivalent. It is not, therefore, possible to treat section 1(2)(c) as the implementation of that provision and section 1(2)(b) as providing merely an additional and purely domestic remedy.”
“The second basic principle concerns the interpretation and application of a provision of United Kingdom legislation which is inconsistent with a directly applicable provision of Community law. Where such an inconsistency exists the statutory provision is to be read and take effect as though the statute had enacted that the offending provision was to be without prejudice to the directly enforceable Community rights of persons having the benefit of such rights. That is the effect ofsection 2 of the European Communities Act 1972 … 17. Accordingly, if an inconsistency with directly enforceable Community law exists, formal statutory requirements must where necessary be disapplied or moulded to the extent needed to enable those requirements to be applied in a manner consistent with Community law.”
“A woman is to be regarded as employed on work rated as equivalent with that of any men if, but only if, her job and their job have been given an equal value or her job has been given a higher value, in terms of the demand made on a worker under various headings (for instance effort, skill, decision), on a study undertaken with a view to evaluating in those terms the jobs to be done by all or any of the employees in an undertaking or group of undertakings, or would have been given an equal value, or her job would have been given a higher value, but for the evaluation being made on a system setting different values for men and women on the same demand under any heading.”
