Infectious disease outbreaks can present serious challenges for employers and employees. Events such as seasonal influenza outbreaks, norovirus incidents, or large-scale public health emergencies like COVID-19 highlight the importance of workplace health protection and risk management. In England and Wales, employers have clear legal duties to protect staff, contractors, customers and visitors from foreseeable health risks, including the spread of infectious diseases.

These responsibilities arise primarily from health and safety legislation, employment law, and equality law. Failure to manage infectious disease risks appropriately can lead to enforcement action by regulators, employment tribunal claims, and potential civil claims for compensation. This guide explains the legal framework governing infectious disease control in workplaces, the duties placed on employers, and practical steps organisations can take to comply with the law.

The Legal Framework Governing Workplace Health During Disease Outbreaks

Several pieces of legislation govern employer responsibilities during infectious disease outbreaks.

Health and Safety at Work etc. Act 1974

The cornerstone of workplace health protection in Great Britain is the Health and Safety at Work etc. Act 1974. This legislation requires employers to ensure, so far as reasonably practicable, the health, safety and welfare of employees and others affected by their work activities.

This duty extends beyond employees and includes agency workers, contractors, customers, and visitors to the workplace. Employers must ensure that work activities do not expose these individuals to unnecessary health risks.

In the context of infectious diseases, this duty requires employers to take reasonable steps to prevent workplace transmission where risks are foreseeable.

Management of Health and Safety at Work Regulations 1999

These regulations require employers to:

• Carry out suitable and sufficient risk assessments.
• Identify hazards such as infectious diseases.
• Implement control measures to reduce risks.
• Provide appropriate information and training to staff.

Risk assessment is a central requirement. Employers must assess workplace hazards and implement measures to control them effectively.

Other Relevant Regulations

Depending on the nature of the outbreak and workplace activities, additional regulations may apply, including:

• Control of Substances Hazardous to Health Regulations 2002 (COSHH) – particularly where workers may be exposed to biological agents.
• Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR) – requiring reporting of certain work-related infections or exposure incidents.
• Workplace (Health, Safety and Welfare) Regulations 1992 – requiring adequate ventilation, hygiene and welfare facilities.

Risk Assessments During Infectious Disease Outbreaks

A central legal requirement during any disease outbreak is conducting a risk assessment.

Employers must evaluate:

• How the disease spreads (for example airborne, contact or surface transmission).
• The likelihood of exposure in the workplace.
• Which workers may be most at risk.
• Measures required to reduce transmission.

Risk assessments should be updated whenever circumstances change. For example, new public health guidance or an outbreak within the workforce may require additional control measures.

Government guidance emphasises that workplaces should continue to apply health and safety obligations and adopt proportionate steps to reduce infection risks, including improved hygiene and ventilation.

Implementing Infection Control Measures

Once risks are identified, employers must take reasonable steps to minimise exposure. Measures will vary depending on the workplace but often include the following.

Hygiene and Cleaning Measures

Employers should ensure workplaces are kept clean and hygienic. This includes:

• Regular cleaning of frequently touched surfaces
• Providing handwashing facilities and sanitiser
• Promoting good respiratory hygiene among staff

Maintaining cleanliness helps reduce transmission of many respiratory and contact-based infections.

Ventilation and Workplace Environment

Good ventilation is an important control measure for airborne infections.

Employers must ensure adequate ventilation under workplace safety regulations. Improving airflow and reducing crowded spaces can significantly reduce infection risks in indoor environments.

Personal Protective Equipment (PPE)

Where risks cannot be adequately controlled by other measures, employers may need to provide protective equipment such as:

• Masks or respirators
• Gloves
• Protective clothing

PPE requirements are particularly relevant in healthcare, laboratories, and environments where workers may be exposed to biological hazards.

Protecting Clinically Vulnerable Workers

During infectious disease outbreaks, some employees may face higher health risks due to underlying medical conditions.

Employers should consider whether additional protections are required for clinically vulnerable staff. Measures may include:

• Adjusting work duties
• Allowing remote work where possible
• Providing enhanced protective measures

If a worker's condition qualifies as a disability under the Equality Act 2010, employers may be legally required to make reasonable adjustments to reduce workplace risk.

Failure to consider such adjustments could lead to discrimination claims in employment tribunals.

Consulting Employees and Safety Representatives

Health and safety law requires employers to consult employees or their representatives on matters affecting workplace safety.

This consultation should cover:

• Identified risks
• Proposed safety measures
• Changes to workplace practices

Effective consultation helps ensure that employees understand safety measures and cooperate with them.

Workers also have legal responsibilities to follow safety instructions and report hazards.

Managing Workplace Outbreaks

If multiple employees become ill with an infectious disease, employers may need to take additional action to contain the outbreak.

Typical steps may include:

• Encouraging symptomatic employees to stay at home
• Allowing remote working where possible
• Increasing cleaning and hygiene measures
• Reviewing workplace ventilation
• Communicating guidance clearly to staff

Although not every outbreak must be formally reported, some cases linked directly to workplace exposure may need reporting under RIDDOR.

Employers should seek public health guidance where appropriate.

Reporting Obligations and Regulatory Enforcement

Certain work-related infections must be reported to the Health and Safety Executive (HSE) under RIDDOR where occupational exposure is suspected.

For example, reporting may be required when:

• An incident at work exposes workers to an infectious agent.
• A worker contracts a disease due to workplace exposure.

Regulators can investigate workplace safety failures and take enforcement action where necessary.

Legal Risks for Employers

Failure to manage infectious disease risks appropriately may expose employers to several forms of legal liability.

Health and Safety Enforcement

Regulators such as the Health and Safety Executive may issue:

• Improvement notices
• Prohibition notices
• Criminal prosecutions

Serious breaches of health and safety law can result in substantial fines.

Employment Tribunal Claims

Employees may bring tribunal claims in situations such as:

• Dismissal for refusing unsafe work
• Discrimination against vulnerable workers
• Detriment for raising health and safety concerns

Civil Claims for Compensation

In some circumstances, employees who suffer illness due to workplace exposure may pursue negligence claims in the civil courts seeking compensation.

Such claims typically require evidence that the employer failed to take reasonably practicable steps to prevent the risk.

Time Limits for Bringing Legal Claims

Different types of claims are subject to strict time limits.

For employment tribunal claims, most cases must be filed within three months less one day from the relevant act or dismissal, subject to the early conciliation process.

Personal injury claims in the civil courts generally have a three-year limitation period from the date of injury or knowledge of the injury.

Because time limits are strict, individuals considering legal action should act promptly.

Practical Steps Employers Can Take to Comply With the Law

Employers seeking to manage infectious disease risks effectively should consider the following steps:

1. Conduct comprehensive workplace risk assessments.
2. Implement appropriate infection control measures such as hygiene, ventilation and distancing where necessary.
3. Provide training and clear information to employees.
4. Encourage staff to report symptoms and stay home when ill.
5. Consider additional protections for vulnerable employees.
6. Keep up to date with public health and regulatory guidance.
7. Document actions taken to demonstrate compliance with health and safety duties.

These measures help protect both employees and organisations from legal risks.

Common Questions About Workplace Infectious Disease Responsibilities

Can employees refuse to work if they believe the workplace is unsafe?

Employees have certain protections under health and safety law if they reasonably believe they face serious and imminent danger. However, each situation depends on specific facts.

Can employers require staff to stay home if they are infectious?

Employers can usually require employees to stay away from work if this is necessary to protect workplace health and safety.

Are employers required to provide remote working?

There is no universal legal requirement to offer remote working during disease outbreaks. However, it may be considered a reasonable safety measure in some circumstances.

Do employers need to report workplace infections?

Only certain work-related exposures or diseases must be reported under RIDDOR. Ordinary community transmission usually does not require reporting.

Summary

Employers in England and Wales have a legal duty to protect employees and others from workplace health risks, including infectious disease outbreaks. These duties arise primarily under the Health and Safety at Work etc. Act 1974 and supporting regulations requiring risk assessments, infection control measures, employee consultation and appropriate reporting of workplace incidents.

During outbreaks, employers must take reasonably practicable steps to reduce transmission risks, protect vulnerable staff and maintain safe working conditions. Failure to meet these responsibilities can lead to enforcement action, tribunal claims or compensation claims.

By conducting thorough risk assessments, implementing proportionate safety measures and maintaining clear communication with staff, employers can comply with the law while protecting workforce health.
