Why is hand hygiene essential for your business?

Written by Harry Wood

The health of your employees can have a direct impact on your business’s health if you can reduce the spread of seasonal illnesses, coughs, colds and even upset stomachs. As hands are a primary vector for spreading disease-causing pathogens, effective hand hygiene is the simplest, most cost-effective way to help prevent illness.

For businesses across all sectors, employee illness carries a significant financial burden by increasing absenteeism and presenteeism. This is when employees show up to work with physical or mental health issues, rather than taking sick leave, which impacts their ability to work effectively and can also risk the spread of seasonal illnesses like the flu to other colleagues.

Implementing a targeted hand hygiene programme is not merely a preventative measure; it is a strategic investment that can reduce preventable illnesses and deliver substantial financial returns.

How diseases are spread by hands in work environments

While many people may instinctively think of the washroom as the primary place where infections are likely to originate, the reality is that the most hotspots are often the ones we touch most frequently and clean least effectively. These high-touch surfaces, such as door handles, lift buttons, and shared kitchen appliances, are typically located throughout the workplace, at communal junctions where many people can leave their microbial signatures.

Any surface that facilitates hand-to-surface or surface-to-hand contact is a potential site for cross contamination and the spread of illnesses. Understanding these zones is the first step towards reducing the spread of handborne infections.

Typical hotspots for transmission of infections

The first surface that people usually touch at work is the door into the building itself, which is often just one of the many door handles they need to touch to navigate the office, i.e. the workspace, meeting rooms, kitchens, washrooms and toilet cubicles. The communal areas of an office typically have multiple hotspots, including the buttons on the coffee machine, the doors of the microwave or fridge, the shared milk carton, and the kitchen and washroom taps, all of which are touched by many employees during the day, creating multiple points for the spread of gastrointestinal and respiratory diseases.

In the modern office environment, the practice of hot-desking has turned shared workspaces into transmission hubs. Although not as commonly shared these days with the widespread use of laptops, research consistently shows that office keyboards and mice can harbour large numbers of bacteria. The desk surfaces, chairs, cables and monitors are now the main shared surfaces in many offices.

The impact of presenteeism and absenteeism

Poor employee health significantly impacts businesses through both absenteeism (missing work) and presenteeism (attending work while sick). A study in the US found that the indirect costs of these exceeded direct medical costs by 2–3 times. The financial impact of an infection sweeping through a workplace is measured in lost billable hours, missed deadlines and operational paralysis.

Presenteeism not only reduces the sick employee’s productivity but also increases the risk of spreading illness to colleagues via the common surfaces mentioned above, which are found throughout the work environment. The real danger is the multiplier effect of a “heroic” employee who goes to work while ill and puts colleagues at risk, potentially increasing absenteeism.
Absenteeism caused by illness can negatively affect the broader team, adding to colleagues’ workloads, increasing stress and lowering overall workplace morale.

The return on investment of a targeted hand hygiene programme

Studies have shown that by implementing targeted hand hygiene programmes, such as providing alcohol-based hand sanitisers and desk wipes, businesses — and even the military and schools — can dramatically reduce absenteeism and presenteeism:

A group of office workers provided with sanitiser and wipes experienced a 13.4% lower incidence of absences.
A US Army training facility found a 44% reduction in lost training time after installing hand sanitiser stations.
A school handwashing education programme reduced gastrointestinal illness-related absenteeism by 29–57%.

The most common infections caused by poor hand hygiene

A large number of infections can be spread via surfaces in business environments. Here is a brief overview of some of the common ones:

1. Gastrointestinal infections

Commonly called stomach bugs, these can be the most disruptive to businesses because they spread rapidly and have a rapid impact on the person infected.

Norovirus: This is highly contagious and the leading cause of “stomach flu”. Only 10–100 virus particles are needed to cause an infection. The virus can survive for up to 12 hours on hard surfaces and is highly resistant to hand sanitiser.
Salmonella & E. coli: These bacteria are more often associated with food preparation. They are frequently spread when employees don’t wash their hands properly after using the washroom or from handling raw food ingredients.
Hepatitis A: A serious viral liver infection that can be spread by infected food handlers. It can lead to long-term illness and result in significant legal and reputational risks for hospitality businesses.

2. Respiratory diseases

These are primarily airborne but can be picked up by touching surfaces where respiratory droplets from an infected person have landed, or the infected person touched after coughing or sneezing into their hands.

Influenza. The flu virus can survive on hard surfaces for 24–48 hours. Touching a contaminated surface and then the nose or mouth is a transmission route, although it is also transmitted through the air.
The common cold: Caused by a group of rhinoviruses, it is a major cause of short-term absenteeism and is also spread by the airborne route.
Strep throat: While often spread via coughs, the Streptococcus bacteria that cause strep throat can survive for months on dry surfaces.

3. Skin and eye infections

These are spread through direct physical contact or shared equipment.

Staphylococcus aureus (including MRSA). These bacteria live on the skin and can enter through tiny cuts and cause infection. Like other “gram-positive” bacteria, they can also survive for months on dry surfaces.
Conjunctivitis (Pink Eye): An infection of the membrane that lines the eyelid and eyeball, it can be caused by many bacteria and viruses, but is extremely contagious. It is mainly spread by touching a contaminated surface and then rubbing the eyes.

Creating a culture of hand hygiene

Investing in improved hand hygiene for a business involves not just providing the right soaps, sanitisers and hand drying facilities, but creating a cultural shift. To truly benefit, hand hygiene should not be a directive, but a frictionless, instinctive part of the workday. By combining behavioural science with high-quality supplies, you can ensure that the practice is maintained and the general wellbeing of employees is improved.

The power of the nudge

People’s hand hygiene practices are heavily influenced by their daily habits, their perception of their own ability to maintain hygiene and what they expect the outcomes of preventive measures to be. Poor adoption of good practices is often rooted in a lack of knowledge, an unawareness of risks or misconceptions.

Conversely, educating them on how protective actions prevent illness helps people to change their behaviour. Hand hygiene behaviour is strongly influenced by the organisational culture and the influence of role models, such as colleagues or superiors.

To help the change, businesses can use nudges, subtle, low-cost environmental cues that make the right choice the easiest one.

Transition points: Place sanitiser dispensers where people change environments, such as at the entrance to the building, outside lifts and at the doors of shared meeting rooms.
Decision points: Situate hygiene stations near high-touch “reward” areas. Placing a dispenser next to the communal coffee machine or at the start of a buffet line captures users at the exact moment they are most likely to transmit or receive germs.
Visual cues: Simple floor decals (such as footprints leading to a sink) or eye-level icons near door handles act as mental tripwires, triggering the habit of sanitising without requiring a conscious effort.

Go for quality over quantity

A common mistake is providing staff with the cheapest soap available, as frequent washing or sanitising can cause skin to become dry, cracked or irritated, so employees may subconsciously avoid handwashing to prevent discomfort. A good quality soap that is kind to the skin is always recommended.

Providing high-quality soaps and sanitisers helps people maintain good practices:

Increases compliance: If the soap feels and smells premium, the act of washing becomes a pleasant sensory break rather than a chore.
Protects the skin barrier: Intact skin is the body’s first line of defence. Cracked skin caused by harsh chemicals provides an entry point for infections.

Create a healthier future for your business through hand hygiene

Hand hygiene is a fundamental component of business strategy that pays back a return on investment. By addressing the invisible threat of surface-to-hand transmission, you aren’t just preventing the spread of the flu or a stomach bug; you are actively protecting your staff and your business productivity.

Implementing a robust hand hygiene programme provides numerous benefits for any business.

For your employees: It fosters a culture of care and wellbeing, reducing the impact of disease outbreaks and the burden of absenteeism and presenteeism.
For your customers: It builds an immediate sense of trust and brand authority, signalling that you value their safety as much as their business.
Regulatory compliance helps you meet workplace health standards and minimise operational risk.
For your bottom line: It’s a low-cost, high-return insurance policy against the financial cost of presenteeism, absenteeism and lost productivity.

FAQs

Why is hand hygiene considered a strategic investment for a business?

Because hands are a primary vector for spreading disease-causing pathogens, effective hand hygiene is the simplest, most cost-effective way to prevent illness. Implementing a targeted hand hygiene programme is a strategic investment that reduces preventable illnesses and delivers substantial financial returns by lowering absenteeism and presenteeism.

What are the main germ hotspots in a typical office environment?

Hotspots are typically high-touch surfaces that are cleaned least effectively, often located at communal junctions. These include door handles, lift buttons, shared kitchen appliances (coffee machine buttons, fridge doors) and shared workspaces or hot-desking areas where desk surfaces, chairs, cables and monitors are touched by many employees.

What are the financial consequences of absenteeism and presenteeism?

Poor employee health carries a significant financial burden. The indirect costs of absenteeism (missing work) and presenteeism (working while sick) can exceed direct medical costs by two to three times. This financial impact is measured in lost billable hours, missed deadlines and operational paralysis.

How can a business create a strong culture of hand hygiene among employees?

A strong culture is created by combining behavioural science with high-quality supplies. This includes using “nudges”, such as placing sanitiser dispensers at transition points (building entrance, outside lifts) and decision points (near the coffee machine). Providing high-quality soaps and sanitisers also increases compliance by protecting skin and making the act pleasant.
