Solidarity has disputed the constitutionality of the Amendment Bill on Employment Equity in court papers, where it urged that the law is contrary to international labour conventions and where it accused government of being in contempt of the conventions. The trade union announced on Wednesday that it has served summons on President Cyril Ramaphosa, the Department of Employment and Labour, Employment and Labour Minister Thulas Nxesi, the Director-General of Employment and Labour Thobile Lamati, as well as the Employment Equity Commission.
