This article examines various economic and sociopolitical perspectives on reducing working hours in the current context. Six main approaches are analysed: the income-leisure choice of neoclassical economics, the distributive conflict of Marxist political economy, the optimization of production processes, the centrality of reproductive work in feminist economics, ecological considerations, and post-work theories. The article shows how these perspectives, often complementary but sometimes contradictory, offer a complex and multifaceted view of the issue. It concludes that the confluence of factors such as technological changes, environmental concerns and new conceptions of work is driving a renewed debate about reducing working hours, posing challenges and opportunities for transforming work organization in contemporary society.
