Long-term sickness absence: a framework for HR

Few situations test an HR team like a long absence. The employee is unwell and often anxious; the manager is worried about the team and unsure what they're allowed to ask; and every week that passes without a plan makes the eventual return harder. The good news is that managing long-term absence well is not mysterious. It is a sequence of sensible, humane steps applied consistently – and organisations that follow them keep far more of their people. Here is a practical framework, from the first weeks of an absence through to a sustainable return.

Step 1: Get the foundations in place

Everything is easier with a clear absence policy that both sides can see. ACAS advises that a policy should set out what's expected of employer and employee alike – how to report sickness, what evidence is needed, how sick pay works, and how the organisation will stay in touch during absence. If your policy uses trigger or review points, make sure managers apply them consistently and remember that adjusting triggers can itself be a reasonable adjustment for a disabled employee. The policy is not there to catch people out; it is there so nobody has to improvise during a stressful situation.

Step 2: Stay in contact – by agreement

The most common failure in long-term absence is silence. Managers worry that contact will look like pressure, so they say nothing – and the employee, hearing nothing for weeks, concludes they've been forgotten or written off. ACAS guidance is straightforward: employers should agree how and when to make contact during an absence, make sure the person's work is covered while they're off, and talk about ways to support their return.

Agree the arrangements with the employee: how often you'll be in touch, whether by phone, email or message, and who makes contact. Keep the conversations human – how they're doing, what's changed at work that they'd want to know, whether anything would help. An employee doesn't have to share anything about their condition, and shouldn't be pressed to; but open, low-pressure communication makes everything that follows easier.

Step 3: Bring in occupational health at the right moment

There comes a point in most long absences where the employer needs more than a fit note: a clear picture of what the person can and cannot do, what would help, and how long recovery might realistically take. That is the job of an occupational health referral. ACAS notes that an occupational health assessment is a useful addition to a doctor's report precisely because it focuses on the person's actual job – how their health affects the work, and how the work might affect their health.

The right moment is earlier than most employers think. If the absence looks likely to be lengthy, if a return date is unclear, if the same condition keeps recurring, or if adjustments are being considered – refer. You don't need a diagnosis to make a referral; uncertainty is the reason to make one. Handle it openly: discuss it with the employee first, share the referral, and frame it as what it is – expert advice to help you support them.

Step 4: Hold a proper return-to-work conversation

When a return comes into view, resist the temptation to simply put the person back on the rota. ACAS recommends a return-to-work meeting as good practice: a chance to check they're ready, update them on anything that's changed, look at any recommendations from their doctor or the occupational health report, and agree what support they need. If the person is disabled, this is also where reasonable adjustments should be discussed and agreed.

It's worth asking one more question in that meeting: what would they like colleagues to know, and what should stay private? Handled well, that single question prevents a great deal of awkwardness on day one.

Step 5: Build the return as a transition

For anything beyond a short absence, the two tools that make a return stick are the phased return and reasonable adjustments. ACAS describes a phased return as a gradual build-up to normal working – reduced hours, lighter duties, or different work during the transition – with the shape and length agreed between employer and employee and reviewed regularly. Pay needs agreeing too: someone doing their usual job on reduced hours should get their usual rate for the hours worked, while different or lighter duties need a rate agreed in writing.

Where the employee is disabled under the Equality Act, adjustments are a legal duty, not a courtesy – and they can extend to the absence process itself, such as adjusting trigger points or recording disability-related absence separately so the person isn't disadvantaged by it.

Step 6: Review, and know your obligations

Long-term conditions fluctuate. Build review points into every stage – during absence, at the return meeting, through the phased return and beyond – and be ready to adjust. If a return falters, that's a prompt for more support and possibly a further occupational health review, not a failure. And if, after sustained effort, a return doesn't prove possible, the process you've followed matters enormously: acting without up-to-date occupational health advice, or without having properly considered adjustments, is exactly what tribunals examine. Doing this well protects the employee first, and the organisation with them.

The framework at a glance

Most long absences end well when they're managed with structure and warmth in equal measure. If you'd like support putting this framework into practice – from a single referral to full absence management support – our team works with employers across the South East to do exactly that.
