What are the implications of art.14 of the European Convention on Human Rights: the prohibition of discrimination?

UK legislation currently prohibits discrimination on grounds of sex, marital status, pregnancy and maternity, gender reassignment, race, colour, nationality, national or ethnic origins, age, disability, sexual orientation, religion or belief, and trade union membership or non-membership. Whether or not workers can use art.14 in aid of a contention that they have suffered unlawful discrimination remains to be seen.
