E/C.12/VEN/CO/3 sufficient to ensure a decent standard of living for workers and their families and at the fact that there is no transparent system of indexation and adjustment (art. 7). The Committee recommends that the State party ensure that the national minimum wage is reviewed by means of an effective and transparent system of indexation and adjustment and set at a level sufficient to ensure a decent standard of living for all workers and their families. The Committee reminds the State party of the importance of transparent tripartite negotiations between State authorities, elected representatives of workers and employers in establishing an effective system for setting the minimum wage. Trade union rights 20. The Committee takes note with concern of reports of acts of violence and intimidation against trade union leaders and members. The Committee is also concerned about interference by some State authorities in the election of trade union representatives (art. 8). The Committee urges the State party to protect trade union rights and effectively investigate all reports of violations of trade union rights that are brought to its attention. The Committee recommends that the State party review the legal provisions restricting the right of trade unions to freely elect their representatives. Social security 21.
