Employment Law and Sickness – what UK employers need to know
Employment law and sickness can be a difficult area for employers to manage. Most businesses want to support staff who are unwell, yet they also need to maintain productivity and control absence. The challenge is finding a fair and lawful balance.
In my experience, sickness absence often becomes complicated when communication breaks down. Employers may assume an employee is not engaging, while the employee may feel unsupported. This can lead to grievances, stress, and sometimes tribunal claims. Because of this, a structured and thoughtful approach is usually the safest option.
Employment law and sickness: your legal duties as an employer
Employment law and sickness places several responsibilities on employers. These include monitoring absence, maintaining contact, and considering reasonable adjustments where appropriate. However, the law does not require employers to tolerate unlimited absence.
A key principle is fairness. Tribunals will often consider whether the employer acted reasonably in the circumstances. This includes whether medical evidence was obtained and whether alternatives were explored before dismissal.
For example, I recently advised a company where an employee had repeated short term absence. The employer dismissed quickly, believing the situation would not improve. However, the tribunal later found that the business had not explored medical support or adjustments. This weakened their defence.
Employers should therefore focus on evidence and process, rather than assumptions.
Short term and long term sickness absence
It is useful to distinguish between short term and long term absence. These situations often require different approaches.
Short term absence usually involves intermittent periods of sickness. This can affect operational planning and may raise concerns about reliability. A structured absence policy and return to work meetings can help address patterns.
Long term sickness generally involves continuous absence. In these cases, employers should seek medical advice and maintain regular contact. The aim is to understand prognosis and whether a return to work is realistic.
In both scenarios, consistency is important. Similar cases should be treated in similar ways.
Managing sickness absence fairly
Good management is often the key to reducing risk under employment law and sickness. Clear policies and early communication can prevent disputes.
Employers should consider the following:
- Keeping accurate absence records
- Holding return to work meetings
- Obtaining occupational health advice
- Reviewing adjustments or support
These steps show that the employer is engaged and reasonable. They also provide evidence if decisions are later challenged.
Guidance from ACAS can help employers design a fair absence management approach.
Employment law and sickness – Disability and reasonable adjustments
A significant risk area under employment law and sickness is disability discrimination. Where a medical condition meets the legal definition of disability, employers must consider reasonable adjustments.
This may include flexible working, changes to duties, or a phased return. What is reasonable will depend on the size and resources of the organisation.
I often see employers focus only on attendance. However, tribunals usually expect a broader view. The question is whether adjustments could have enabled the employee to continue working.
Even where adjustments are not possible, documenting the consideration process is essential.
Can you dismiss an employee for sickness?
Yes, dismissal may be lawful under employment law and sickness where absence becomes unsustainable. However, the process must be fair.
Employers should normally:
- Obtain medical evidence
- Consult with the employee
- Consider alternative roles
- Review adjustments
Only once these steps have been explored should dismissal be considered. The reason will usually be capability rather than misconduct.
A common mistake is rushing the process. I have advised businesses where the employee later returned to full health. This created the perception that the dismissal was premature.
Fit notes and occupational health
Medical evidence plays an important role in decision making. Fit notes provide initial guidance, but they are often limited. Occupational health reports may give a clearer view of prognosis and adjustments.
Employers sometimes worry about the cost of medical advice. However, this investment can reduce legal risk and support fair outcomes.
Regular review meetings should also take place. These show that the employer is actively managing the situation.
Practical steps to reduce risk – Employment law and sickness
Managing absence well can improve morale and reduce claims. Employers should focus on consistency and transparency.
For example:
- Train managers in absence handling
- Ensure policies are up to date
- Communicate clearly with employees
- Document decisions carefully
Many of the businesses I support seek ongoing free employer employment law advice so they feel confident dealing with complex absence cases.
Ultimately, employment law and sickness does not prevent employers from managing attendance. It simply requires a fair and structured approach.
Final thoughts for UK employers
Sickness absence is part of working life. Most employers will face difficult decisions at some stage. By focusing on fairness, evidence, and communication, you can protect your business and support your workforce.
Taking time to plan and review each case often leads to better outcomes. It also shows employees that decisions are made thoughtfully rather than reactively.
