E/C.12/GTM/CO/3 Informal labour and domestic work 15. The Committee notes with concern the large number of workers in the State party who are employed in the informal sector of the economy. The Committee regrets the existence of the special regime for domestic employees, which restricts a number of labour rights which are statutory for other workers (arts. 6 and 7). The Committee urges the State party to continue doing everything possible to reduce the informal sector of the economy in order to encourage work in the formal sector and thus ensure that all workers are able fully to enjoy their economic and social rights. The Committee recommends that steps be taken to ensure full legal protection for workers, regardless of the sector in which they are employed. It also recommends that the State party ratify the ILO Domestic Workers Convention, 2011 (No. 189) and its Domestic Workers Recommendation, 2011 (No. 201). Trade union rights 16. The Committee is concerned about the existence of restrictions on the exercise of the right to form trade unions and to exercise trade union rights. The killings of numerous trade unionists, the perpetrators of which often go unpunished (art. 8), are of particular concern to the Committee. The Committee recommends that the State party take steps to ensure that the right to form trade unions and to exercise trade union rights are respected, as established in article 8 of the Covenant. It further recommends that the State party take effective measures to ensure that workers are protected from any reprisals on account of their involvement in trade unions. The Committee urges the State party to investigate all cases of killings of trade unionists and to punish the perpetrators. Social security 17. Despite the Committee’s previous recommendation (E/C.12/1/Add.93, paras. 17 and 35) and the incentives introduced by the State party to increase the number of persons registered with the Guatemalan Social Security Institute, the Committee notes with regret that only 22.1 per cent of workers are covered by the State party’s social security system. In particular, the Committee regrets the State party’s failure to ensure social security coverage for agricultural and domestic workers (art. 9). The Committee recommends that the State party take the necessary measures to guarantee broad social coverage that ensures appropriate benefits for all workers, including agricultural and domestic workers, taking into consideration the Committee’s general comment No. 19 (2008) on the right to social security (article 9 of the Covenant). The Committee also recommends that the State party consider establishing social protection floors (see the ILO Social Protection Floors Recommendation, 2012 (No. 202)) for the realization of the right to social security. Economic exploitation of children 18. Despite the reduction in child labour, the Committee reiterates its concern about the continuing economic exploitation of children in the State party, especially in agricultural and domestic services (E/C.12/1/Add.93, paras. 20 and 38). The Committee notes with concern that the poverty of rural households and limited access to secondary education increase the risk of child labour (art. 10). The Committee encourages the State party to redouble its efforts to combat the problem of child labour by means of an emergency plan. It urges the State party to conduct systematic labour inspections and to implement public policies aimed at GE.14-23900 5
