Phased Return to Work: Build Your Plan

A phased return is a temporary arrangement where you come back to work on reduced hours or lighter duties, building gradually to your normal role. It usually follows a longer absence – after surgery, a serious illness, or a period off with stress or a mental health condition – but it can follow any absence where going straight back to full duties would be too much.

There is no legal right to a phased return and no fixed formula for how one should work. It is an agreement between you and your employer, usually informed by what your doctor has written on your fit note. That sounds vague, and it is – which is why having a written plan to propose puts you in a far stronger position than asking for “a gradual return” and hoping.

Most run between two and six weeks. The general principle is that the longer you have been off, the longer and gentler the build-up should be:

• Off under a month – often two weeks is enough, typically starting at around 60% of your normal hours.
• Off one to three months – around four weeks, starting at roughly half your normal hours.
• Off three to six months – around six weeks, starting at about 40%.
• Off more than six months – eight weeks or more, starting at about a third and building slowly. After a very long absence, occupational health input is worth asking for.

These are starting points, not rules. What matters more than the schedule is that it is written down, agreed, and reviewed – a plan that turns out to be too ambitious should be adjusted rather than abandoned.

There are two ways to reduce hours: shorter days across your normal working week, or fewer full days. Shorter days are the more common starting point, because keeping to your normal weekly rhythm helps rebuild routine and makes the return feel less like a cliff edge. Three-hour days across five days is a classic first week.

Fewer, longer days can work better for some jobs – shift work, roles with a long commute, or work that needs a full day to be useful. And for fatigue-related conditions, spreading rest days between working days often matters more than the total. Our planner suggests short days by default; swap it if the other pattern suits you better.

This is the question people worry about most, and the honest answer is that it depends on your employer.

• Pay for hours worked – the most common arrangement. You are paid your normal rate for the hours you actually do, so a 50% week means roughly 50% pay.
• Full pay throughout – some employers, particularly larger ones with an occupational sick pay scheme, pay full pay for the whole phased return. Check your contract or staff handbook.
• Topped up with sick pay – some employers pay for the hours worked and make up part of the gap with contractual or statutory sick pay for the hours you are still unfit to work.
• Using annual leave – you can ask to use holiday to cover the unworked hours so your pay stays whole. Your employer does not have to agree, but many will.

Statutory Sick Pay can still apply during a phased return in some circumstances, since you remain partly unfit for work. If money is going to be the deciding factor in whether you can afford to return gradually, raise it before the plan is agreed rather than after. Work out your sick pay.

A fit note has two options: “not fit for work”, or “may be fit for work taking account of the following advice”. The second is what enables a phased return. The doctor can tick any of four suggestions – a phased return to work, altered hours, amended duties, or workplace adaptations – and add a comment about what would help.

A “may be fit” note is advice, not an instruction. Your employer does not have to follow it, and if they cannot accommodate the suggestions, the note is treated as though it said “not fit for work” and you stay off. In practice, most employers would far rather have you back on reduced hours than not at all.

If you need a fit note that supports a phased return after a shorter absence, we can issue one the same day after a video consultation with a GMC-registered doctor. Get a fit note online.

If you have been off for several months, the doctor who has been issuing your fit notes is best placed to write the one that supports your return – they have your history and know the case. Our same-day service is aimed at shorter absences, and at people who need a fit note quickly and cannot get a GP appointment in time. For long absences, ask your employer about an occupational health assessment as well: it carries weight, and it gives them a clinical opinion to act on.

• Build the plan first – turn up with specifics rather than a general request. The planner above gives you week-by-week hours you can put in an email.
• Put it in writing – email is fine. Set out the proposed hours, the build-up, and a review date.
• Ask for a review point – a fortnight in is sensible. It gives both sides permission to adjust without it feeling like failure.
• Get the outcome recorded – whatever is agreed should go on your return to work form.
• Say what you can do – frame it around what you are able to contribute, not what you cannot. It is a more persuasive conversation and a more accurate one.

Coming back too fast is common, and it is not a failure – it is information. If the plan is proving too much, say so early and ask to hold the current level for another week or step back a stage. That is a smaller problem than a second period of absence.

If your employer is refusing a reasonable phased return and your condition counts as a disability, they have a legal duty to consider reasonable adjustments, which can include changed hours. Acas can advise, and occupational health input often unlocks the conversation because it gives the employer a clinical opinion to act on.
