Long-term sickness: your UK employee rights

Long-term sickness — typically 4+ weeks of continuous absence — triggers additional UK employee protections beyond ordinary sick leave. The Equality Act 2010 requires employers to make reasonable adjustments if your condition qualifies as a disability, which covers most conditions lasting or expected to last 12+ months. Employers should refer to Occupational Health for an independent medical view + adjustment recommendations. Capability dismissal is possible after long absence but requires a proper process — consultation, OH assessment, consideration of alternatives, warnings + appeal rights. This guide covers your rights during long-term absence, reasonable adjustments, occupational health, phased return + unfair dismissal grounds.

What counts as long-term sickness

  • No fixed definition
  • Typically 4+ weeks continuous absence
  • Employer's policies may define differently

Equality Act 2010 protections

Your condition is a disability if: - Physical or mental impairment - Substantial + long-term (>12 months or likely) - Adverse effect on normal day-to-day activities

If disability applies, employer must: - Make reasonable adjustments - Not directly discriminate - Not indirectly discriminate (unless justified) - Not victimise for asserting rights

Reasonable adjustments

Typical examples: - Phased return / reduced hours - Altered duties - Working from home - Ergonomic equipment - Modified shift patterns - Time off for medical appointments

Employer must consider requests seriously; refusal without good reason may be disability discrimination.

Occupational Health

Employer may refer you to OH: - Independent medical opinion - Recommendations on adjustments + return-to-work - Prognosis + timeline

You can decline OH referral, but may weaken your position in disputes.

Capability dismissal

Employer can dismiss for 'capability' if: - Long-term absence with no realistic prospect of return - All reasonable adjustments explored - Proper process followed: 1. Consultation with employee 2. OH referral + report 3. Consideration of alternatives 4. Formal warnings + review meetings 5. Right of appeal

Skipping steps = unfair dismissal claim.

Ill-health early retirement

Some pension schemes (especially public sector) allow ill-health early retirement: - Immediate access to pension - Enhanced benefit if unable to work - Tier system based on likelihood of return

Unfair dismissal claim

If dismissed unfairly: - Employment tribunal within 3 months - ACAS conciliation first (mandatory) - Compensation: basic award + compensatory award (capped) - Reinstatement possible but rarely ordered

  • Employment and Support Allowance (ESA) after SSP ends
  • Universal Credit
  • Personal Independence Payment (PIP)

In short

Long-term sickness triggers Equality Act protections + reasonable adjustment duty. Capability dismissal requires proper process. ESA + UC support after SSP ends.

Frequently asked questions

What are reasonable adjustments?

Changes employer must make if you have a disability under Equality Act 2010 — phased return, altered duties, ergonomic equipment, working from home, etc.
