UK Civil Servants Threaten Strike Over Four Day Week

Britain's largest Civil Service union is preparing a new industrial action ballot over pay and working conditions, seeking a four-day working week without reduced salaries and a 10 percent pay increase. The Public and Commercial Services union (PCS) plans to begin voting on October 20, alongside demands for greater job flexibility and additional annual leave.

The PCS also wants stronger protections for employees working from home and a formal right to disconnect from work outside working hours. According to reports published by The Telegraph and The Spectator on October 12, the union is urging members to support industrial action if negotiations fail to address its demands.

For the ballot to meet the required threshold, at least half of eligible PCS members must participate, with a majority of those voting supporting industrial action. Changes introduced through Angela Rayner's Employment Rights Act removed the previous requirement that at least 40 percent of the total workforce vote in favor of industrial action.

The union has pursued a shorter working week for several years. Its first national ballot on the issue took place in November 2022, followed by industrial action across government departments and agencies, including the Department for Work and Pensions, Border Force, the Land Registry and HM Revenue and Customs.

PCS campaigns director Dan Durcan said the union believed evidence supporting reduced working hours was strengthening.

"Civil servants have a responsibility to be objective. The evidence about the economic and social benefits of a four-day week grows ever more convincing."

Durcan said the forthcoming vote could have significant implications for working arrangements across the country.

"PCS members will soon vote on taking industrial action on a four-day week. This could result in one of the most significant changes to working life in the UK in over a century."

The proposal comes as some local authorities explore shorter working weeks. Lambeth council announced a four-day-week trial earlier in October, while Hackney and Lewisham may also consider similar arrangements. South Cambridgeshire council previously became the first local authority to adopt a permanent shorter week, allowing certain employees to receive full pay for 80 percent of their contracted hours.

However, the national government has previously rejected the principle of paying public employees their full salaries for substantially reduced working hours. The average full-time Civil Service salary reached £38,770 in 2026, compared with £36,760 in 2025 and £26,760 in 2016, according to official figures cited by The Telegraph.

Mike Wood, the shadow minister for the Cabinet Office, opposed the union's demands and called on ministers to resist the proposed changes.

"Taxpayers' money should not be wasted on this. But it is no surprise that unions feel emboldened to take this action, having been empowered by Labour's Employment Rights Act. Labour Ministers must make clear that they do not support a four-day week on full pay for civil servants and stand firm against any strike action."

A Cabinet Office spokesperson said the government would continue discussions with unions while considering public finances.

"The Government is committed to recognising the hard work of civil servants, while ensuring public sector pay remains sustainable. Discussions will continue with Civil Service unions, including PCS, as part of departments' ongoing engagement."

Separately, Northern Ireland's public healthcare workforce is facing another potential industrial dispute over pay and staffing. The public services union Nipsa announced plans to ballot healthcare members from October 21, citing unresolved pay demands and concerns about working conditions.

Nipsa assistant secretary Kevin Kelly said members were increasingly frustrated with staffing pressures, delayed pay decisions and proposed spending reductions.

"Our members are telling us they have had enough of being asked to do more with less while services are cut, staff go unrecognised and pay issues remain unresolved."

Kelly also pointed to continuing disputes over the 2026-27 pay award and the extension of the Real Living Wage to care-sector employees. Northern Ireland's Department of Health estimated that implementing the pay award and extending the wage would cost approximately £280 million, while the department faces a projected deficit of between £800 million and £1 billion.

Nipsa said its ballot would close the following month. The separate dispute highlights continuing pay and workforce pressures across parts of the UK's public services, although the healthcare action concerns different demands from the PCS campaign for a four-day working week.
