In Argentina, labor unions have opposed a proposal to repeal Law 2717, which governs Sunday rest, demanding statistical evidence to justify such a move. Meanwhile, in Honduras, officials have defended the Part-Time Employment Law passed in March 2026, which regulates reduced workdays to integrate informal workers into the formal economy with social security protections. In El Salvador, the Superior Labor Council is evaluating modernization proposals, including a 4/3 work model that would increase daily shifts to 11 or 12 hours to allow for longer weekends. This has met resistance from unions citing concerns over fatigue. In Mexico, legislative initiatives have been introduced to mandate quarterly reporting on the effects of the country’s transition from a 48-hour workweek toward a 40-hour limit, intended to monitor productivity and employment indicators through 2030. ## Timeline ### 2026-09-17: Labor reforms under review in El Salvador and Mexico Labor reforms are progressing in El Salvador and Mexico, with discussions in El Salvador regarding 12-hour shifts for longer weekends, and a Mexican proposal to monitor the transition to a 40-hour workweek. 9 sources. https://clstr.news/cluster/labor-reforms-under-review-in-el-salvador-and-mexico ### 2026-09-08: Labor law debates emerge in Argentina and Honduras Labor rights face scrutiny in Argentina over a proposed repeal of Sunday rest laws, while Honduras implements new part-time employment regulations to protect worker rights and formalize labor. 2 sources. https://clstr.news/cluster/labor-law-debates-emerge-in-argentina-and-honduras --- Cite as: Latin American labor law and working hour reforms.
