Phased return to work after sickness: your rights and pay

Back surgery, long Covid, cancer treatment, a winter flu that turned into months off. Coming back at full speed on day one is how people relapse. A phased return lets you build hours, duties or pace back up step by step, but only if your employer agrees the plan and you agree the pay.

A phased return in plain terms

A phased return is a temporary, agreed plan to come back below your full contract while you recover. Fewer days. Shorter shifts. Lighter duties. A slower pace in the same role. Lighter till duties instead of stacking shelves, supernumerary shifts on a ward, no night work for a fortnight. The shape and length are for you and your employer to agree together, and Acas says to review the plan regularly and keep it flexible.

How long it runs is for the two of you to agree, and a fit note often sets the timescale. Long Covid, musculoskeletal injuries and cancer recoveries often need longer, with a review date written in from the start. Nothing about it changes your contract unless you both agree in writing. You stay employed on your normal terms, you keep accruing holiday, and if the plan fails you fall back onto sick leave rather than full duties.

The fit note: what your clinician can actually write

The fit note, the Med 3, has two outcomes only. Either you are “not fit for work” or you “may be fit for work”. There is no certificate that declares you fit, and you never need a note signing you back in.

When your GP, nurse, physio, pharmacist or occupational therapist ticks “may be fit for work”, they can tick four kinds of help: a phased return, altered hours, amended duties, and workplace adaptations such as working from home, plus a free-text comment. Since 2022 all five professions can issue notes, not only doctors. The first seven calendar days of any absence are still self-certification.

That advice is advisory. The government guidance to employers says it plainly: this is advice, and you are not obligated to agree. You can return before the note expires without going back to the clinician first.

Can your employer refuse a phased return?

Yes, unless a stronger right applies. There is no free-standing statutory right to reduced hours on return. If your employer says they cannot accommodate the adjustments, the same fit note is treated as if it said “not fit for work”. You stay off sick, sick pay continues under the same rules, and you do not need a new note.

A refusal still has consequences. Ask for the reason in writing. If the reason is cover, cost or “we do not do that here”, keep that message. It matters later if your condition counts as a disability, because then the refusal is judged under the Equality Act, not employer goodwill. If you are in a union, send the refusal to your rep the same day. USDAW for retail, Unite for warehouses and logistics, UNISON or the RCN for health and care, GMB across many low-paid sectors. If you are not in one, Acas and Citizens Advice are free and you can talk to them before you raise anything formally.

Pay during a phased return: the part most people get wrong

Hours you work are paid at your normal rate. Hours or days you do not work have no automatic right to full pay. What fills the gap is whatever you agree: full pay if the employer offers it, company sick pay if your contract gives it, SSP on qualifying days, booked holiday, or unpaid leave. Get the mix in writing before your first shift back. A one-line email counts: which days, which hours, which rate, review date.

SSP follows one hard rule. It is paid only for full non-working days. Work any part of a day and there is no SSP for the rest of it, however short the shift. Acas gives the exact example: Jan normally works seven hours a day, three days a week, and on a phased return works two hours a day for two days. No SSP for the five lost hours on either day. SSP is payable on the third day, the fully non-working one, if Jan is eligible. Plan around that. Whole days off beat half days for SSP, every time. Our Statutory Sick Pay calculator shows the daily figure once you know your qualifying days.

Since 6 April 2026 SSP starts from the first day of sickness. The three waiting days are gone. The lower earnings limit is gone too, so zero-hours and low-hours staff qualify whatever they earn. The rate for 2026/27 is the lower of 80% of your average weekly earnings over the previous eight weeks or £123.25 a week. The daily rate is that weekly figure divided by your qualifying days. Our full breakdown is in the Statutory Sick Pay guide.

Two winter truths follow. A flu absence that starts now runs straight onto paid SSP from day one, which changes the maths of staying home when you are infectious. And a worker earning £122.10 a week who got nothing before April 2026 now gets 80% of that, £97.68 a week, because the earnings floor was abolished.

The same logic decides the nurse’s plan below. Three full shifts with Tuesday and Thursday fully off keeps two SSP days alive. Five half days kills SSP dead and halves the wage too.

If your condition is a disability, the law gets sharper

A phased return is a suggestion for most people. For a disabled worker it can be a duty the employer owes. A disability under section 6 of the Equality Act 2010 means a physical or mental impairment with a substantial, long-term effect on day-to-day activities, where long-term means 12 months or more or likely to last that long. Cancer, HIV and multiple sclerosis count automatically from diagnosis. Long Covid can count if its effects are substantial and long-term, which for many sufferers with fatigue, breathlessness and post-exertional relapse they are.

Where that applies, sections 20 to 21 require the employer to make reasonable adjustments where a practice, a physical feature or a missing aid puts you at a substantial disadvantage. A phased return, altered hours, amended or lighter duties, and adapted equipment are textbook adjustments. Refusing a reasonable plan is discrimination, whatever the goodwill. Section 15 adds a second shield: unfavourable treatment because of something arising from disability, such as a warning or dismissal triggered by disability-related absence, is unlawful unless the employer proves it is a proportionate way to achieve a legitimate aim, and only if they knew or should have known about the disability. There is no qualifying service for either claim. Read the longer guide to reasonable adjustments for disabled workers.

Take the nurse after long Covid, £35,000 a year, average weekly earnings £673.08, SSP capped at £123.25. Monday, Wednesday and Friday worked with Tuesday and Thursday fully off gives three days’ wages of £403.85 plus £49.30 of SSP, £453.15 total. Half days every day gives £336.54 in wages and no SSP, £116.61 worse. If her fatigue meets the disability test, the trust must engage with that structure properly, take occupational health advice, and think about discounting disability-related absence from its triggers. The retail worker after cancer treatment is in the strongest position of the three. On £12.71 an hour for 16 hours over four days, her weekly SSP is £123.25, £30.81 on each full non-working day, and her disabled status from diagnosis means a refused phased return can be a section 21 breach on its own.

Holiday keeps building while you are off or phasing back

Statutory holiday of 5.6 weeks, 28 days for a five-day worker, accrues through sick leave and through a phased return at your contracted rate, not the reduced hours you are temporarily working, unless you agree in writing to change your contract. Four months fully off still banks about 9.3 days.

If sickness stopped you taking leave, regular-hours staff can carry over up to four weeks, 20 days, and irregular-hours and part-year workers can carry over up to 28 days. Acas says the carried-over days must be used within 18 months of the end of the leave year they came from. You can also ask to take holiday during sick leave and be paid holiday pay instead of SSP, which on a phased return is often the smart move when the SSP day rate is £24 or £30 against a full day’s wages.

Occupational health and Access to Work: who helps, who pays

There is no statutory right to occupational health, but your employer can refer you with your consent and can be expected to do so before any big decision about your return or your job. A GP report needs your consent under the Access to Medical Reports Act 1988, and you can see it first. You cannot be made to produce evidence beyond the fit note. Good referrals follow NICE and HSE practice: a coordinated written plan, a named contact, a review date.

Access to Work is the DWP grant that pays for what sits beyond the employer’s own duty: specialist equipment, support workers, travel where public transport is unusable, workplace changes, and mental-health support through Able Futures or Maximus. It never repays, never touches your benefits, and never pays for what the employer should have provided as a reasonable adjustment. Apply early. The National Audit Office found 62,100 applications waiting at March 2025 and average processing of 109 working days in November 2025 against a 25-day target. The annual cap cited for 2024-25 and 2025-26 was £69,260. More in our guide to occupational health.

Absence triggers, warnings and dismissal during a return

Trigger systems such as the Bradford Factor or “three absences in six months” are employer policy. They have no statutory force. Applied mechanically during a phased return they punish the exact wobbles a return involves, and where absence is disability-related they invite section 15 and failure-to-adjust claims. Tribunals expect disability-related absence to be discounted or the trigger adjusted where that is reasonable. If you are warned, check whether the absences counted were disability-related and whether the policy was adjusted. Our guides cover absence triggers and the Bradford factor and discipline while off sick in detail.

Dismissal during or after a phased return is not automatically unfair, but a capability dismissal needs a fair process: up-to-date medical evidence, a prognosis, consultation, and genuine consideration of adjustments and alternative roles. If you are disabled, dismissal without that work risks discrimination with no service requirement. Ordinary unfair dismissal still needs two years’ service until the qualifying period falls to six months for dismissals on or after 1 January 2027. If ill health ends the job, read dismissal because you are ill before you sign anything.

Zero-hours, agency, part-time and self-employed

Status decides what machinery you get. Employees can use the fit-note route, negotiate a phased return, claim SSP on any earnings since April 2026, and accrue holiday. Many zero-hours staff are employees for SSP purposes even if the rota calls them workers, which is exactly who the removal of the earnings floor was aimed at. Agency workers give the fit note to the agency, and both the agency and the hirer can owe adjustments. Part-time staff accrue holiday pro rata and the weekly SSP rate divides across fewer qualifying days, which is why the retail worker above gets £30.81 a day. Genuinely self-employed people sit outside all of it: no fit notes, no SSP, Universal Credit or New Style Employment and Support Allowance instead. If your “self-employment” looks like staff work with a rota, uniform and control, check your employment status and our sick leave rules before you accept nothing.

What to do this week: five steps

1. Get the note right. Ask your clinician to tick “may be fit” and write concrete comments: hours, duties to avoid, pace, reviews. Vague notes get refused.
2. Propose the plan in writing. Days, hours, duties, place of work, pay for each element, review date. Offer whole days off where SSP matters. Keep a copy.
3. Pin down the pay. Wages for worked time, then what covers the rest: company sick pay, SSP on whole days, holiday days, or unpaid. Never start the plan with pay “to be confirmed”.
4. If you may be disabled, say so. Name the condition, its length and effects, and call the plan a reasonable adjustment. Ask that disability-related absence be discounted from triggers.
5. Line up backup. Talk to your union rep, apply to Access to Work early, diary the review, and if you relapse tell work the same day so the absence links to the same period of incapacity.

If the plan breaks down, remember the fallback. A refused or failed phased return puts you back on sick leave on the same note. Linked absences with gaps of 56 days or less count toward the same 28-week SSP entitlement, so keep the fit notes continuous. If warnings or dismissal follow, act fast. Most tribunal claims, discrimination included, now carry a six-month deadline for acts on or after 1 October 2026, after Acas early conciliation pauses the clock.

What changed and what is still coming

1. 6 April 2026SSP from day one, no earnings floor

   Waiting days abolished and the lower earnings limit removed. Rate is the lower of 80% of average weekly earnings or £123.25 a week. Already in force across Great Britain and mirrored in Northern Ireland.

2. April 2026Fair Work Agency established

   The new agency takes complaints about pay and work rights, including minimum wage. Whether it enforces sick pay yet is unconfirmed, and its live practice is unproven, so treat it as a reporting route, not yet a rescue.

3. 1 October 2026Tribunal time limits doubled

   Most employment tribunal claims, including discrimination and unlawful deduction claims, move to six months less one day for acts on or after this date. Scotland breach-of-contract claims follow on 9 November.

4. 1 Jan 2027Unfair dismissal after six months, not two years

   The qualifying period for ordinary unfair dismissal is scheduled to fall from two years to six months for dismissals on or after this date. Zero-hours reforms and wider flexible-working changes are also scheduled for 2027, with dates unconfirmed. Nothing in the pipeline creates a standalone right to a phased return.
