Up to 9.6 million UK workers could see expanded sick pay under rule changes the Trades Union Congress is advocating, according to analysis The Guardian reported this week.

The TUC, the UK's umbrella body for trade unions, published the estimate as part of its push to reform statutory sick pay (SSP). The Guardian's headline did not publish the methodology behind the figure or identify the legislative route the union backs, leaving HR directors with a policy signal rather than a compliance timeline.

What does 9.6 million mean in scale?

Britain's workforce numbers roughly 33 million, putting the TUC's estimate close to a third of all employees. A coverage swing of that size moves the issue from the edge of HR planning into payroll configuration, absence policy, and cost modelling.

The workers the TUC has historically flagged as excluded from SSP — those earning below qualifying thresholds, those yet to complete waiting-period requirements, and those in sectors with irregular hours — make up most of that 9.6 million. Any reform that loosens entry conditions would push eligible headcounts up from day one of absence rather than from week four.

What compliance questions should HR raise now?

Without a published effective date, three operational areas warrant early review:

• Payroll eligibility logic: UK payroll platforms calculate SSP against HMRC-set thresholds. A threshold change forces a configuration review across affected pay runs and a recalculation of historical absences within any new window.
• Policy and contract language: Standard employment contracts reference SSP at the statutory minimum. Employers with enhanced occupational schemes will need to confirm the floor sits above the new statutory minimum and update handbooks and signature cycles accordingly.
• Line-manager briefing: SSP queries route through line managers before they reach HR. Expanded eligibility will increase first-call volume across distributed sites and the need for refresher guidance.

Why can't employers wait for the legislation to pass?

Statutory sick pay operates as a floor, not a ceiling. Most FTSE-listed employers already run occupational sick pay schemes that exceed the statutory minimum, so the TUC's reforms would rebase the floor under existing enhancements rather than introduce a fresh cost line. For those organisations, the work centres on policy alignment and contract audit.

Smaller employers — particularly in hospitality, social care, and retail, the sectors the TUC's analysis most often highlights as high-exclusion — would absorb a more direct cost where discretionary sick pay and unpaid absence have been the default. HR teams in those sectors should map their headcount against the TUC's target categories to size the financial exposure before any implementation timetable firms up.

What signal should HR teams watch next?

The Guardian's reporting stops short of an implementation date or a statement from the Department for Business and Trade. The next signal will come from either a published consultation response, an HMRC technical note to payroll software developers, or a formal impact assessment. Each artefact would convert the 9.6 million figure into a specific compliance deadline employers can plan against.

Until then, the TUC's analysis sets the policy stakes. HR directors who want a head start should ask two questions of their payroll providers: what configuration changes a threshold amendment would require, and what share of their own headcount falls inside the category the TUC is targeting.
