Spain’s 35-hour week collides with a 7% staff shortfall and 2030 retirement cliff
Madrid is quietly rewriting the rules of public-sector work while the clock ticks toward a demographic implosion. Negotiators for the central government and the main civil-service unions accelerated talks this week to lock in a 35-hour week starting 2026 and, in the same breath, decide how many new bodies they are willing to pay for. The answer, at least in the first draft circulating in the ministries, is roughly 27 000 state posts—about the same headcount the cabinet approved for 2025. The unions are already calling the number delusional.
Cutting weekly hours from 37,5 to 35 shaves 7,1 % off the labour supply overnight. In a private company you automate or raise prices; in Spain’s Administración General del Estado you either hire or surrender services. The Social Security registry, the SEPE unemployment offices and the Immigration network—three units already gasping under backlogs—warn that they will need thousands of extra pairs of hands to keep current waiting times from ballooning. Their internal simulations show that the regularisation of hundreds of thousands of undocumented residents planned for late 2026 could add 30 % more face-to-face appointments in some provinces.
The grey tsunami no one budgeted for
Behind the staffing spreadsheets hides an even uglier forecast. A 2020 Función Pública audit revealed that two-thirds of central-government employees were 50 or older; the average age was 51,3. By 2030 more than half of today’s workforce—56,8 %—will hit retirement. The clerical C2 category will lose 72 % of its staff; the mid-grade C1 corps will see 62 % walk out. Even if every position on the 2026 list were filled tomorrow, the system would still be bleeding experience faster than it can pour rookies in.
The maths gets worse. Roughly 5 700 labour-entry posts authorised in previous offers have never been called; another 3 200 internal-promotion slots are frozen in bureaucracy. Add the 20 000 net jobs CSIF says disappeared during the austerity decade and you start the race with a 30 000-place handicap. Unions want the 2026 offer to overhire, not merely replace, and they want selection exams launched the same year the posts are budgeted—something that last happened in 2018.
From replacement to reinvention
Government negotiators argue that shorter hours will modernise the state, improve work-life balance and, in theory, make public service attractive to younger talent. The part they leave out is money. Each additional 1 000 employees costs around €45 million a year in wages and social security; treasury officials have already told spending departments that room for manoeuvre is tight until the 2024 deficit closes. The unions counter with a fiscal mirror: every euro not spent on staff today converts into longer queues, slower benefit payouts and, eventually, higher political cost.
Meanwhile, offices that operate on shift patterns—prisons, coast-radio towers, 24-hour IT helpdesks—must redesign rosters so that the new 35-hour ceiling does not breach EU working-time rules. The 40-hour special shifts will shrink proportionally, meaning night differentials and holiday calendars get reopened plant by plant. One personnel director at the Tax Agency joked privately that they will need two calendars: one for citizens and one for civil servants.
The government hopes to publish the final offer after Easter. Union leaders have set their own deadline: if the document does not include a clear over-recruitment clause and a calendar for calling stalled exams, they will walk. The last time they did, in 2022, the cabinet blinked and added 4 000 extra places. Whether that trick works again depends on how loudly the demographic alarm rings in the finance ministry’s ears. By 2030 the same alarm will sound like a retirement party—unless Madrid hires big, and hires now.
