Working with shingles: What Organisations Need to Know

Shingles-related absence is both an infection‑control risk and an operational issue. Organisations must balance people care with legal duties. This means preventing avoidable exposure (especially among vulnerable groups), apply fair sickness processes, and plan safe, phased returns that minimise disruption and cost.

In practice, that means understanding how shingles spreads at work, who is at risk, how long people are infectious, and what good HR and line‑management decisions look like.

What is shingles?

Shingles (herpes zoster) is caused by reactivation of an infection in nerve tissue after a previous having chickenpox. It typically presents itself with a painful rash and can be accompanied by malaise, fever, headache and other symptoms.

Symptoms usually evolve over 2–4 weeks, with blistering lesions that dry and crust over. The affected skin can remain painful after the rash resolves, particularly in older people.

Why this matters for organisations (infection control & duty of care)

A person with active shingles can transmit chickenpox (not shingles) to a non‑immune colleague through direct contact with blister fluid until all lesions have crusted (typically ~7 days). This is a material workplace risk for pregnant staff, immunosuppressed people and anyone without prior immunity. Organisations must assess and manage this risk as part of their general duty to protect health and safety.

To support your people, it is important to signpost people to accessible, rapid clinical advice and confirmation of diagnosis. Early antiviral treatment can shorten symptom duration and complications, so giving people access to expert diagnosis, review and care via things such as a Virtual GP can ensure quick diagnosis and effective decisions.

What causes shingles?

After primary infection with chickenpox, the virus remains dormant and can reactivate decades later, with risk increasing with age and immunosuppression (e.g., chemotherapy, HIV, high‑dose steroids).

It can often be cause by certain conditions or treatments like chemotherapy. Or, in some instances, it can be caused by stress. So, if your organisation’s workplace culture is one of high stress that doesn’t prioritise mental wellbeing or conduct throughout stress risk-assessment, your people could be at risk.

Public‑health reports estimate that the prevalence of shingles in in older demographics (e.g., 70–79 years) in England and Wales at is approximately 790–880 per 100,000 per year. This clearly underlines the likelihood of cases of shingles in the workforce, especially among older workers where the risks are considerably more costly.

Contagious in the workplace

• Main transmission route: contact with vesicle fluid. Those who have never had chickenpox (or vaccination) are at risk of developing chickenpox after exposure.

• Infectious period: from rash onset until all lesions are dry/crusted (often ~7 days, sometimes longer). Covering lesions reduces exposure risk but does not replace exclusion where colleagues are pregnant or immunosuppressed.

• Organisational legal duty: assess the risk and take reasonable steps to prevent exposure, consistent with HSE infection‑at‑work guidance.

Where exposure of a pregnant or immunosuppressed colleague is suspected, prompt clinical advice is required. This might be from the UK Health Security Agency (UKHSA) guidance details regarding post‑exposure prophylaxis (PEP) pathways in at‑risk groups.

Should an employee with shingles come to work?

• High‑risk settings/roles (e.g., healthcare, care, close contact with vulnerable people): staff should not attend work until lesions have crusted, to avoid exposing pregnant or immunosuppressed individuals.

• Non‑clinical/low‑risk settings: attendance may be possible if the person feels well enough and lesions can be fully covered, but they must avoid contact with any vulnerable colleagues and should not attend if systemic symptoms (e.g., fever) are present.

Key compliance points

• People who are off sick with shingles can self‑certify for the first 7 calendar days; from day 8, a fit note is required. Fit notes can be issued by doctors, nurses, pharmacists, physiotherapists and occupational therapists.

• If a fit note says “may be fit for work”, organisational HR and leadership teams should discuss suggested adjustments (e.g., remote work, covering lesions, avoiding vulnerable contacts, reduced hours). If adjustments aren’t practicable, treat as “not fit for work.”

• Record decisions and review dates; seek clinical clarity where needed (e.g., Occupational Health Assessment) to confirm restrictions and timelines.

Advice to give employees

• Seek prompt medical advice: If an individual suspects they have shingles, they should seek an expert opinion or diagnosis as antivirals are time‑sensitive and may reduce complications.

• Suggest a continued absence if an individual has a fever or feels unwell, and avoid contact with pregnant or immunosuppressed colleagues until lesions have crusted.

• Cover all lesions completely (clothing/dressings) and practice strict hand hygiene to minimise contamination risk.

• Discuss adjustments with the individual and if they are deemed “may be fit for work” on their fit note (e.g., remote work, different duties, flexible hours).

How long should a person stay off work with shingles?

Typical course: the rash/blistering phase usually resolves within 2–4 weeks, but people are infectious until all lesions have crusted (often around 7 days from rash onset). If lesions cannot be covered or the role involves contact with vulnerable people, do not attend until crusting is complete.

Complications extend timelines: ocular involvement or post‑herpetic neuralgia can prolong recovery and impair function, requiring longer absence or additional adjustments; obtain clinical guidance before resuming normal duties.

Fit‑note and policy points: apply self‑certification for 7 days and a fit note from day 8; plan a phased return where pain, fatigue or residual symptoms affect capacity. Keep a clear record of decisions and review dates.

Workplace infection‑control actions for organisations

Risk‑assess immediately: identify whether the person’s role involves contact with vulnerable groups (pregnant colleagues, immunosuppressed people, neonates, or anyone without varicella immunity) and whether all lesions can be fully covered while at work.

Controls in low‑risk settings: where the person feels well, lesions are completely covered, and contact with vulnerable colleagues can be avoided, limited on‑site working or temporary remote work may be feasible; continue to avoid close contact with vulnerable groups until crusting.

Hygiene & cleaning: reinforce hand hygiene and standard precautions; these measures reduce the chance of contaminating surfaces, complementing (not replacing) exclusion of risk‑exposed staff.

Escalation for at‑risk exposures: if a pregnant or immunosuppressed colleague has been exposed, seek urgent clinical advice; UKHSA provides post‑exposure prophylaxis (PEP) pathways for susceptible, high‑risk groups.

Recording decisions, legal duties and disclosure routes

Organisations must assess and control infection risks at work as part of their general health‑and‑safety duties. This means they must maintain an audit trail of decisions (risk assessment, adjustments, exclusion dates, and review points) and handle any health data confidentially.

If people raise concerns about unsafe practices, it is best practice to provide them with a confidential channel to discuss any concerns and find a solution.

Reasonable adjustments and short‑term support

Where fit‑note advice indicates the person “may be fit for work”, agree temporary adjustments (for example, remote work, alternative duties with no close contact with vulnerable individuals, flexible hours to manage pain/fatigue) and set review dates; if adjustments are not practicable, treat as “not fit for work.”

Whatever the case, be sure to keep in touch with individuals to an appropriate level during sickness. Once they are deemed fit to work, it is necessary to hold a return‑to‑work meeting to confirm capacity and any required support. This meeting can be used to revisit risk controls and phased hours.

Vaccination & prevention

UK public‑health guidance confirms shingles risk increases with age and immunosuppression. If individuals feel the need to seek a vaccination, they may be signposted to the UK vaccination programme which now uses non‑live Shingrix®, with expanded eligibility for severely immunosuppressed adults (18+).

Amongst older individuals, there may be a more phased roll‑out to support long‑term risk reduction efforts among that section of the population. This does not necessarily have to be part of an organisation's health and safety policy, but could be useful in reducing risk to people in the workforce.

Phased return‑to‑work planning

If infectious lesions cannot be covered or the role involves contact with vulnerable people, the safest course is to remain off‑site until crusting, then plan a graded return as pain and fatigue allow.

At the return-to-work meeting, agree time‑limited adjustments (e.g., reduced hours, limited in‑person contact, alternative duties) with review dates. If necessary, be sure to seek input from an Occupational Health advisor in instances where recovery is prolonged (e.g., post‑herpetic neuralgia or ocular involvement).

Managing wider impacts on wellbeing and costs

Shingles pain, fatigue and sleep disruption can impair concentration and mood, increasing presenteeism risk. Swift clinical care, access to quick GP referrals using a Virtual GP in combination with counselling support can reduce absence durations and improve the quality of return-to-work processes.

How an EAP reduces shingles‑related absences

Shingles may be a short‑term condition for most people, but unmanaged cases create infection‑control risks, avoidable absence, and significant operational disruptions. This is particularly true in workplaces where workloads are already stretched.

An organisational response must therefore provide fast clinical clarity, consistent leadership decision‑making policies, and safe return‑to‑work processes. This is where HA | Wisdom Wellbeing’s clinically governed EAP provides measurable value.

With access to expert HR and management support, your leadership teams can access expert guidance on implementing adjustments, handling disclosures and confidentiality, deciding whether on‑site working is safe and planning legally compliant, phased returns. This closes the gap identified in workplace guidance where many managers are unprepared to manage sickness processes confidently.

To support people who may be struggling with shingles or any other issues, with the Wisdom Super Care EAP package, you can provide your people access to our Virtual GP in association with Livi - Europe’s largest digital-first healthcare provider.

If the suspect they may be struggling with the symptoms of shingles, they can bypass long NHS waiting lists and get quick referrals to seek diagnosis and any necessary medical support or prescriptions. As well as access to a Virtual GP, your organisation will also be able to access Occupational Health assessments to support on any necessary suggestions and to smooth the return-the-work process and keep your organisation legally compliant.

With our EAP, your organisation can ensure faster recovery, fewer absences, safer, legally compliant decisions making all while minimising risk.
