What is occupational health?
Occupational health is a specialist field dedicated to promoting health and wellbeing in the workplace. This means supporting employers and employees to create safer environments and reduce the risk of hazards. Occupational health professionals operate at the crossroads of health surveillance, psychology, ergonomics and first aid to make sure people can succeed in their roles while remaining healthy and productive.
Why understanding occupational health terminology matters
Occupational health can feel overwhelming if you are unfamiliar with the language. You may find yourself navigating assessments, referrals and reports without being entirely sure what each term means or why it matters. Much like learning the vocabulary of any specialist area, understanding key phrases helps demystify the process. Employees gain clarity about their own health and work adjustments, while employers become better equipped to interpret advice, comply with regulations and communicate with occupational health providers. So let’s take a look at some of the common occupational health terminology.
Fit for work assessment
A fit for work assessment is one of the most common touchpoints between employees and occupational health professionals. At its simplest, it asks whether someone is currently capable of carrying out their job safely and effectively. However, what often surprises people is that the answer is rarely a simple yes or no. Occupational health specialists consider the nature of the role, the employee’s health condition and any adjustments that might enable them to continue working. Rather than excluding people, these assessments aim to open up possibilities by identifying safe, sustainable ways of working.
Reasonable adjustments
This term appears frequently in employment law and occupational health discussions, yet it sounds more complicated than it really is. A reasonable adjustment is any change that helps an employee with a health condition or disability carry out their role without disadvantage. It could be altering working hours, modifying equipment or offering phased returns after sickness absence. What counts as “reasonable” depends on the company’s size, resources and the needs of the individual. The guiding principle is fairness, ensuring that health conditions do not become barriers to employment.
Sickness absence management
When an employee is away from work due to illness, sickness absence management is the structured process that helps employers support the individual, while also planning for business continuity. Occupational health plays a key role by advising on expected recovery times, identifying any underlying causes and recommending supportive measures for returning to work. Contrary to popular belief, this process is not about rushing people back but about using clinical insight to ensure that any return is safe and appropriate.
Ergonomic assessment
Ergonomics focuses on designing workspaces, tools and tasks to fit the individual rather than forcing the individual to fit the environment. An ergonomic assessment examines posture, equipment setup and work habits to reduce strain and prevent injuries such as back pain or repetitive strain injuries. In an era where hybrid working is increasingly common, ergonomic assessments are no longer limited to traditional office settings. They now include home offices, factory environments and any other space where work takes place.
Health surveillance
Some workplaces expose employees to potential health risks such as noise, vibration, hazardous substances or dust. Health surveillance is the ongoing monitoring required to detect early signs of work-related ill-health before they become serious. It may involve hearing tests, lung function checks or skin assessments depending on the risks involved. By identifying issues early, employers can take action to reduce exposure and prevent long-term harm. Surveillance is not optional in many industries, it is a legal requirement under UK health and safety legislation.
Return to work plan
A return to work plan outlines the steps an employee will take when coming back after sickness absence. It maps out support needs, phased hours, modified tasks and review points. A well designed plan provides reassurance for both the employee and employer, ensuring that the return is gradual and manageable. Occupational health contributes by offering evidence based recommendations and forecasting how an individual’s work capacity is likely to evolve during recovery.
Clinical referral
Sometimes additional expertise is needed to understand a health condition fully. A clinical referral is when occupational health directs an employee to another specialist, such as physiotherapists, mental health professionals or physicians with expertise in particular conditions. This referral is not about removing responsibility, but about increasing the quality of information required to make workplace decisions. It ensures that any advice is rooted in the most accurate and up to date clinical insight.
Workplace risk assessment
Risk assessment is a familiar term in many organisations, yet its connection to occupational health is often misunderstood. A workplace risk assessment identifies potential hazards that could cause harm and evaluates the likelihood and severity of those risks. Occupational health contributes insights into how health conditions interact with work environments, ensuring that assessments reflect the needs of real people rather than theoretical situations. This strengthens safety measures and creates more inclusive workplaces.
Occupational health report
After an assessment, employers typically receive an occupational health report. This document summarises clinical findings, outlines whether the individual is fit for work and recommends adjustments or support measures. Importantly, it does not disclose confidential medical details. Instead, it translates health information into practical workplace guidance. For employees, this confidentiality is vital. For employers, it provides clarity without overstepping privacy boundaries.
Case management
Complex health situations may involve multiple reviews, referrals and a staged return. Case management describes the coordination of this process. It ensures that communication remains clear, timelines are maintained and all parties understand their responsibilities. Effective case management can significantly reduce uncertainty and prevent miscommunication during extended periods of ill health.
Choosing an occupational health provider
Selecting the right occupational health provider can shape the health culture of an entire organisation. Employers should look for clinically qualified professionals, with a strong understanding of industry regulations. It is also important to choose a provider that values partnership. Occupational health works best when the provider understands the organisation’s environment, challenges and workforce. A responsive service, ethical confidentiality practices and evidence-based guidance are essential foundations for trust.
Final thoughts
Occupational health is an essential part of modern working life, helping employees stay healthy and employers meet their responsibilities. Understanding the terminology removes uncertainty and allows everyone involved to communicate more effectively. From fit for work assessments to reasonable adjustments and health surveillance, each term plays a role in creating safer, more supportive workplaces.
