Recognizing Impairment and Determining Fitness for Work

This review examines the critical importance of assessing functional capacity of employees in the context of workplace impairment and fitness to work. It highlights how employment serves as a key determinant of both physical and mental health while exploring the multifaceted relationship between work, health, and well-being.

CoRE Insights

Work is a fundamental determinant of health. Employment can offer financial stability, social connections, and a sense of purpose, which may influence physical and mental health. Therefore, maintaining a healthy work environment is considered important for recovery and well-being.
Assessing fitness to work requires a holistic approach. Evaluations should integrate health status, functional capacity, skills, and work environment, using biopsychosocial models rather than focusing solely on impairment or diagnosis to assess fitness for work.
Workplace accommodations are essential. Modifying duties, schedules, and the work environment can help sustain work ability for employees with impairments, supporting safe and productive workforce participation.

Research Overview

This review adopts a narrative review methodology, integrating findings from published research, and occupational health frameworks to explore the concept of fitness for work. The authors reviewed literature across occupational health, vocational rehabilitation, and workplace safety to highlight how work ability is shaped by physical health, mental health, and workplace environmental demands. The review links research insights with practical recommendations for workplace policy. It highlights how employment serves as a key determinant of both physical and mental health and discusses the complex relationship between work, health, and well-being.

Key Findings

The review finds that work is a critical determinant of health and well-being. An employee’s fitness for work should be assessed through a biopsychosocial approach, meaning that it should consider workers’ abilities, health, and job demands. Work ability is dynamic, often shaped by illness, injury, and even workplace conditions. Standard functional assessments are often too biomedical, which overlook environmental and occupational factors and may not represent the holistic abilities of an employee. Risk, capacity, and tolerance are especially important in safety-sensitive roles, while workplace accommodations such as modified duties and flexible schedules are vital to sustaining participation and productivity.

Fitness for work is determined by a worker’s ability to perform job tasks safely, with attention to both risk to self and others.
Work ability is often dynamic and should balance individual capabilities with occupational demands. Ensuring employees have work that is appropriate to their current abilities is vital for health promotion, injury prevention, and vocational rehabilitation.
Functional assessments should move beyond biomedical models and include environmental and task demands, providing objective evidence to inform work accommodations.
Risk, capacity, and tolerance are interconnected factors in assessing fitness for work, especially in safety-sensitive and decision-critical jobs where impairment can have severe consequences.
Comprehensive, biopsychosocial evaluations and workplace accommodations play a crucial role in maintaining employment and enhancing workforce well-being for individuals with temporary or permanent impairments.

How to Take Action

Employers

Make sure those evaluating employee fitness for work use a holistic, biopsychosocial approach. This means assessments should consider the employee’s overall health, functional abilities, skills, and the specific demands of their work environment.
Provide workplace accommodations, such as changing job responsibilities, adjusting work schedules, or modifying the work setting, to help employees use their strengths and participate safely and consistently.
Use thorough functional assessments to gather objective information for decisions. These assessments should balance safety, employee capacity, and job requirements, especially in roles where safety is critical, to protect the well-being of all workers.
