I assume the Deputy is referring to the ILO declaration on fundamental principles and rights at work and its follow-up, which was adopted at the June 1998 International Labour Conference.
This declaration emphasises that all members of the ILO, even if they have not ratified the conventions in question, have an obligation, arising from the very fact of membership in the organisation, to respect, to promote and to realise, in good faith and in accordance with the Constitution, the principles concerning the fundamental rights which are the subject of those conventions, namely, freedom of association and the effective recognition of the right to collective bargaining; the elimination of all forms of forced or compulsory labour; the effective abolition of child labour; and the elimination of discrimination in respect of employment and occupation.
