training, or commuting to facilities of all types. Indeed, the provision of access to appropriate and, where necessary, specially tailored forms of transportation is crucial to the realization by persons with disabilities of virtually all the rights recognized in the Covenant. 24. The “technical and vocational guidance and training programmes” required under article 6 (2) of the Covenant should reflect the needs of all persons with disabilities, take place in integrated settings, and be planned and implemented with the full involvement of representatives of persons with disabilities. 25. The right to “the enjoyment of just and favourable conditions of work” (art. 7) applies to all disabled workers, whether they work in sheltered facilities or in the open labour market. Disabled workers may not be discriminated against with respect to wages or other conditions if their work is equal to that of non-disabled workers. States parties have a responsibility to ensure that disability is not used as an excuse for creating low standards of labour protection or for paying below minimum wages. 26. Trade union-related rights (art. 8) apply equally to workers with disabilities and regardless of whether they work in special work facilities or in the open labour market. In addition, article 8, read in conjunction with other rights such as the right to freedom of association, serves to emphasize the importance of the right of persons with disabilities to form their own organizations. If these organizations are to be effective in “the promotion and protection of [the] economic and social interests” (art. 8 (1) (a)) of such persons, they should be consulted regularly by government bodies and others in relation to all matters affecting them; it may also be necessary that they be supported financially and otherwise so as to ensure their viability. 27. The International Labour Organization has developed valuable and comprehensive instruments with respect to the work-related rights of persons with disabilities, including in particular Convention No. 159 (1983) concerning vocational rehabilitation and employment of persons with disabilities. 23 The Committee encourages States parties to the Covenant to consider ratifying that Convention. C. Article 9: Social security 28. Social security and income-maintenance schemes are of particular importance for persons with disabilities. As stated in the Standard Rules, “States should ensure the provision of adequate income support to persons with disabilities who, owing to disability or disability-related factors, have temporarily lost or received a reduction in their income or have been denied employment opportunities”.24 Such support should reflect the special needs for assistance and other expenses often associated with disability. In addition, as far as possible, the support provided should also cover 23 See also Recommendation No. 99 (1955) concerning vocational rehabilitation of the disabled, and Recommendation No. 168 (1983) concerning vocational rehabilitation and employment of persons with disabilities. 24 Standard Rules (see note 6 above), Rule 8, paragraph 1.
