5 Physical Demands of a Job Employers May be Overlooking

When we think about the physical demands of a job, heavy lifting is the first thing that comes to mind. However, physical demands can extend far beyond moving heavy objects. Job tasks such as repetitive movements, prolonged sitting or standing, awkward positioning and frequent reaching can place physical demands on a worker. While individual tasks in isolation may not appear particularly strenuous, their cumulative effect can make a role more physically demanding than originally expected.

By understanding these often-overlooked physical demands, employers can identify opportunities to protect employee health and wellbeing. This insight also supports informed decisions about any workplace adjustments that may be required. Here are five physical demands of a job that employers may be overlooking.

5 Physical Demands of a Job Employers May be Overlooking

1. Prolonged Sitting or Standing

Sitting or standing for extended periods may not seem physically demanding at first. However, holding the same position for too long can contribute to discomfort and fatigue. This is particularly evident in roles where a worker may be:

• Standing at a service counter.
• Working on a production line.
• Operating machinery or equipment.
• Sitting down at a desk.

When assessing the physical demands of a job, it is important to not only consider what employees are doing but how long they are required to remain in a particular position. Where possible, employers can consider implementing opportunities for workers to change their position regularly, move between tasks or take appropriate movement breaks.

2. Repetitive Movements 

Roles that require workers to repeat the same movement throughout a shift can place significant strain on specific muscles and joints. Repetitive reaching, gripping, lifting, typing or handling objects can also contribute to developing physical fatigue over time. Therefore, the frequency and duration of a task are important factors when an employer is considering the physical demands of a role. Employers should consider whether repetitive demands could be reduced through task variation, job rotation or the use of different equipment.

3. Awkward Postures 

The way in which a worker performs a task can significantly affect its physical demands. Bending, twisting, reaching overhead, extending their arms or maintaining an awkward posture for an extended period can increase the likelihood of physical strain. These demands are often overlooked because the task itself may seem relatively simple. For example, accessing items that are located at floor level or above shoulder height may only take a few seconds each time. However, if this movement is repeated frequently throughout the day, the cumulative physical demands can be much greater. It is important to review the positioning of equipment, storage areas and workstations to see if there is an opportunity to reduce unnecessary awkward postures.

4. Pushing, Pulling and Carrying 

When you are assessing manual handling, it is common to focus primarily on how much an employee is lifting in their role. However, pushing, pulling and carrying can also contribute significantly to the physical demands of a job.

The level of physical demand associated with a certain task can be influenced by factors such as the:

• Weight and shape of an object.
• How far it needs to be moved.
• Frequency of the task.
• Surface it is moved across.

Even objects that are relatively light may become physically demanding when they need to be moved frequently or over long distances. Understanding the full range of manual handling requirements can help an employer identify where equipment, processes or work environments could be modified.

5. Limited Opportunities to Vary Tasks 

The physical demands of a job are not solely influenced by individual tasks; they can also be affected by how those tasks are organised throughout the workday. An employee who performs several different activities may have opportunities to use different muscle groups and change their posture and movement patterns. On the other hand, completing the same physically demanding activity for most of a shift may cause fatigue. Where appropriate, varying tasks can help distribute physical demands throughout the working day. Small changes to task sequencing or opportunities to alternate between activities may help reduce prolonged exposure to physical demands.  

How Can Employers Identify the Physical Demands of a Job?

Understanding the physical demands of a role can be challenging without observing the work that is being performed. A Job Task Analysis can provide a detailed picture of what a worker is required to do, including the physical requirements of individual tasks, movements, postures, manual handling and other factors that may affect the demands of the role. Additionally, workplace assessments can also help employers identify potential risks and opportunities to modify tasks, equipment or the work environment. This information can be particularly useful when:

• Developing or reviewing a person’s suitable duties.
• Supporting an employee’s return to work.
• Assessing the physical requirements of a role.
• Considering workplace modifications.
• Reviewing potential injury risks.
• Designing or redesigning work tasks.
• Supporting an employee whose capacity has changed.

Why Understanding Physical Demands Matters

Understanding the full physical demands of a role allows employers to make more informed decisions about injury prevention, workplace adjustments and return-to-work planning. Looking beyond heavy lifting can reveal less obvious demands that may contribute to discomfort, fatigue or injury over time. By reviewing how tasks are performed, how frequently they occur and how work is organised throughout the day, can create safer and more sustainable ways of working. Recovery Partners can conduct a comprehensive Job Task Analysis to identify the physical demands of a role and recommend safer work practices.
