What does sedentary work mean?
This describes a dimension of work activity characterized by minimal movement and low energy expenditure during working hours. It frequently appears in office tasks, remote customer service, monitoring, or driving, although the specific conditions vary. It should not be confused with an assessment of the total physical activity a person performs outside of working hours.
Nor does it simply mean “working on a computer.” Working with display screens can be combined with meetings, travel, and various other tasks, or it can keep the person in a nearly constant position. The assessment needs to understand this layout and the restrictions that make it difficult to move or change posture.
Difference from an inappropriate posture
The proper fit of the chair, desk, and monitor is important, but a seemingly comfortable posture can be maintained for too long without adjustment. Static posture and limited movement are additional factors beyond geometric adjustment. Therefore, having the correct furniture does not complete the preventive workstation review.
Similarly, simply standing up does not automatically make an activity sufficiently varied. Prolonged standing can create other demands if it remains immobile. The goal is to facilitate an appropriate combination of positions and activities, taking into account the tasks and the individual’s needs.
How to analyze the day
The analysis identifies continuous periods of seated work, opportunities for movement, autonomy, and organizational barriers. It is worth noting meetings, handling calls, response targets, and the distribution of materials. Digital tools can contribute to a continuous sequence of tasks without breaks, especially when constant availability is expected.
Teleworking and variations between days or shifts must also be considered. A workday with occasional travel can alternate with one requiring continuous attention. Consulting with staff helps to understand these variations without the need for intrusive individual monitoring. The information should be collected with a clear preventive purpose and in a proportionate manner.
Changes in the organization
The organization can facilitate task rotation, meetings in appropriate formats, and opportunities to get up or move around when compatible with the activity. Breaks and recovery time should be integrated into a workload that allows for their use. Simply sending reminders is insufficient if meeting objectives prevents interrupting the activity.
Changes should avoid adverse effects, such as increased carrying of loads or the introduction of fall risks. Nor should movement become a competition between people. The intervention should be adapted to diverse abilities and offer alternatives, maintaining a focus on the conditions that the organization can modify.
Adjustable furniture and workstation adjustment
Adjustable furniture can facilitate alternating positions, provided the ergonomic design of the workstation allows for its proper use. Height, reach, screen, keyboard, cabling, and space should all be checked. The adjustments should not introduce instability or force users into awkward positions for their arms or neck.
Implementation requires information on adjustment and use, as well as follow-up. A table that always remains in the same position may indicate a lack of understanding, handling difficulties, or incompatibility with the task. Before attributing this to a lack of motivation, it is advisable to investigate these barriers with the users.
Practical example
An administrative team receives adjustable desks, but continues to work seated for most of the day. Upon review, it is discovered that cables restrict movement and meetings are scheduled without breaks. The purchase had created a partial technical solution, but failed to address the underlying conditions of use.
The company corrects the installation, reviews the meeting schedule, and agrees on alternative activities compatible with the service. It then checks on usage and any reported difficulties. This example demonstrates that preventing sedentary behavior requires consistency between equipment, information, and organization, without relying solely on personal reminders.
Promoting individual habits and needs
Health promotion initiatives can complement workplace interventions, but they must be distinguished from the obligation to control job risks. Encouraging physical activity outside of working hours does not replace proper organization during working hours. Participation in voluntary activities must respect privacy and personal circumstances.
People with adaptation needs should be assessed through the appropriate channels. It is inappropriate to prescribe universal exercises or time limits without understanding their individual circumstances. Discomfort or health problems require professional attention and should not be diagnosed based on time spent in a chair or data from monitoring devices.
Follow-up and scope of the conclusions
Follow-up can assess actual opportunities for alternation, barriers, and the use of measures, combining observation and consultation. It should avoid drawing excessive conclusions: increased use of an adjustable table does not, in itself, demonstrate a clinical outcome. Indicators need to correspond to the purpose and the available evidence.
The INSST guidelines on screens and workstation design support a vision that combines physical, cognitive, and organizational factors. This fact sheet offers general preventive criteria. Specific interventions must consider working conditions and the diversity of individuals, with review of results and adjustments when necessary.
