The 40-Hour Workweek and the Unfinished Equality Agenda

Mexico’s Senate recently approved a gradual reduction of the standard workweek from 48 to 40 hours — a reform framed as a historic step toward modernizing the country’s labor framework. The proposal would reduce the workweek by two hours per year starting in 2027, reaching 40 hours by 2030 without cutting salaries or benefits. Its stated goal is clear: improve quality of life for millions of workers.

Public debate has focused largely on productivity, business costs, and competitiveness. Yet one critical dimension remains underexamined: What will this reform mean for women?

Mexico enters this conversation from a position of structural inequality. Female labor force participation remains below 50%. According to Mexico’s National Occupation and Employment Survey (ENOE), published by INEGI, women’s labor force participation rate has hovered around 46–47% in recent years, significantly below that of men. This gap is not primarily a question of ambition or talent. It reflects a persistent reality: the double shift. Women participate in the formal labor market, but they also shoulder a disproportionate share of unpaid domestic and caregiving work.

That invisible work is not marginal. According to INEGI’s National Time Use Survey (ENUT) and the Satellite Account of Unpaid Household Work, unpaid care and domestic labor represents nearly 24% of Mexico’s GDP, with more than 70% of that value generated by women. In practical terms, this means that many women in Mexico already work well over 60 hours per week when paid and unpaid responsibilities are combined.

Against this backdrop, a shorter workweek may appear to be unequivocally positive. More available time could translate into rest, professional development, entrepreneurship, or family life. But herein lies the central tension: time is not neutral.

If the distribution of unpaid work inside households remains unchanged, the hours freed from formal employment may simply be reabsorbed into additional unpaid caregiving. According to INEGI’s time-use data, women dedicate more than twice as many hours as men to unpaid domestic and care work. Without robust public policies — accessible childcare, eldercare services, and incentives that promote genuine shared responsibility between men and women — the adjustment risks falling, once again, on women.

Reducing working hours does not automatically redistribute responsibilities. And without redistribution, equality remains incomplete. The question, therefore, is not merely labor-related; it is structural.

The 40-hour reform can be a positive measure, but its real impact will depend on whether it becomes part of a broader transformation: the construction of a national care system.

Mexico is not starting from scratch. Concrete proposals already exist to move toward a coordinated and shared-responsibility care framework. Organizations such as México Evalúa have outlined a roadmap that includes formally recognizing care as a right; progressively expanding services; professionalizing and dignifying care work; strengthening data systems to support evidence-based decision-making; and advancing cultural change that redistributes responsibilities both inside and outside the home.

This means moving beyond today’s fragmented landscape of dispersed programs, uneven coverage, and unstable budgets. According to CONEVAL, Mexico’s social policy architecture still faces challenges in coverage, coordination, and continuity of care-related programs. Building care as a fourth pillar of the welfare state — alongside health, education, and social security — would require institutional redesign and sustained public investment.

There is a compelling economic case as well. According to INEGI’s Satellite Account of Unpaid Household Work, unpaid care work accounts for nearly one-quarter of national output. When that burden is concentrated disproportionately on women, the country absorbs a structural cost: lower female labor force participation, higher informality, interrupted career paths, and a loss of talent that ultimately constrains productivity and long-term growth.

For this reason, transitioning toward a care system is not symbolic social policy, it is competitiveness policy. As México Evalúa has emphasized in its public policy analyses, such a system requires a legal framework that recognizes the right to care and to personal time; coordination mechanisms that align responsible agencies; sustained investment in infrastructure and services; and a communication strategy capable of reshaping deeply embedded social norms.

In parallel, labor reform must be accompanied by measures that make shared responsibility tangible. According to OECD comparative data, Mexico still lags behind in the design of balanced parental leave policies that actively incentivize men’s participation in caregiving. Advancing co-responsibility requires leave schemes that do not implicitly assign caregiving to women, as well as dignified working conditions for paid domestic and care workers, a sector that, according to INEGI, continues to operate largely under informal arrangements.

There is also an unavoidable fiscal dimension. According to the Ministry of Finance (SHCP), fiscal space in Mexico remains constrained relative to OECD averages in terms of public spending as a percentage of GDP. If Mexico intends this agenda to be sustainable, it must stop treating care as discretionary social spending and begin recognizing it as strategic investment — investment that frees time, improves well-being, expands formal labor participation, and generates employment. The debate should not center solely on the cost of building a care system, but on the long-term economic cost of continuing without one.

Ultimately, no policy will endure without cultural transformation. Redistributing care means reshaping expectations: that caregiving is not an act of “help,” but of shared responsibility; that work is measured by results rather than hours of physical presence; and that care is no longer invisible in public policy design.

The 40-hour workweek can be a meaningful labor reform. Its true significance, however, will depend on whether Mexico uses this moment to modernize its welfare model and acknowledge that care itself is economic infrastructure.

Progress is not measured only in reduced hours, but in how societies allocate time — and who gains the opportunity to use it.
