Tensions are rising within Spain's coalition government as Sumar pushes for immediate implementation of a reduced 37.5-hour workweek, a key promise from the 2023 elections.

Vice President Yolanda Díaz insists on swift action, rejecting delays proposed by the PSOE, which seeks more time to align with business interests and parliamentary support.

The PSOE argues for a 2026 rollout, while Sumar demands the reform by 2025, citing its importance for workers and coalition stability.

Díaz has publicly criticized the PSOE's stance, marking a shift from her usual preference for quiet negotiations.

The disagreement highlights broader challenges in the coalition, as both parties navigate competing priorities and external pressures.
