A Return-to-Work Plan Isn't Enough: What Happens After the Plan Matters

Why sustainable return to work depends on consistent adjustments, capable managers and conversations that continue long after the paperwork is complete.

A return-to-work plan isn't enough if nobody consistently follows it.

We often talk about creating a return-to-work plan as though writing the plan is the difficult bit.

It isn't.

The real test is what happens on Monday morning. And Tuesday. And three weeks later.

Is the agreed reduced workload still being respected?

Are working hours increasing at the pace that was actually agreed?

Does the employee still have permission to work from home where that forms part of their adjustment?

Has somebody checked whether the plan is working?

And, perhaps most importantly, does the manager feel confident enough to have an honest conversation when it isn't?

A newly published 2026 study gives us an interesting insight into this. Researchers followed 63 employees experiencing persistent post-concussion symptoms alongside their employers and examined several workplace approaches to returning to work.

Having a written return-to-work plan was the most influential factor examined for returning to the same working conditions as before the injury or illness. But there was another important finding. The workplace interventions had their greatest impact when they were applied consistently over time. That distinction matters.

Because there is a considerable difference between an adjustment being agreed and an adjustment becoming part of someone's everyday working reality. The study relates specifically to persistent post-concussion symptoms, so we should be careful not to assume that the exact findings will be identical for cancer, mental ill health, musculoskeletal conditions or other periods of serious illness.

But its message about implementation deserves attention. And it sits within a much wider conversation taking place in UK workplaces. The Government's Keep Britain Working programme has identified return-to-work plans as one of the actions employers should take. But it has also identified fragmented workplace-health provision, limited line-manager capability and poor measurement of return-to-work outcomes as problems that need addressing. Meanwhile, the CIPD's latest Health and Wellbeing at Work research reports that sickness absence has risen to an average of 9.4 days per employee per year — its highest level in more than 15 years.

So perhaps we need to change the question. Instead of asking “Do we have a return-to-work process?” we should be asking “Does our return-to-work process work in practice?”

A beautifully written policy cannot notice that somebody is struggling.

A phased-return spreadsheet cannot recognise that an employee is frightened to say they are exhausted.

An occupational-health recommendation cannot make a manager remember to protect someone's agreed workload.

And an adjustment written into a document cannot challenge the gradual creep back towards “business as usual”.

People do those things.

That is why we believe sustainable return to work has to be more than a process. It needs a clear plan. It needs appropriate professional advice where required. It needs adjustments that are realistic and reviewed. It needs an employee who has a genuine voice in the process. And it needs a manager who has the confidence, capability and permission to keep the conversation going.

Because returning to work is rarely a single event - it is a transition.

And supporting somebody through that transition requires more than getting the paperwork right. It requires us to keep doing what we said we would do — and to be willing to change the plan when the person in front of us needs something different. That isn't lowering expectations, it's good leadership. And, sometimes, it may be the difference between someone simply returning to work and being able to stay there sustainably.
