Work layout for a restricted growth office commercial clerk


The employer is a sheltered workshop for the disabled (WfbM). Included in the service sector achievements of the sheltered workshop are eg. manual and machine assembling and packaging work, metal work, testing work as well as cleaning work (laundry). 200 people work in the sheltered workshop. Of the 200 people 46 belong to full-time staff who accompany and support the disabled people in carrying out their activities.

Disability and functional limitation of the employee:

The man is growth restricted (height 150 cm) and suffers additionally from a spinal disease. His spine is bent laterally and single vertebral bodies in certain areas are stretched and stiff ( Scoliosis). The man has a grade of disability of 100 (GdB 100).

Training and career:

He completed a vocational training as an office commercial clerk in a vocational training centre. After his training he changed to full-time employee or commercial clerk to the sheltered workshop for the disabled.

Work duties and workplace (actual status):

The commercial clerk works in the ordering section of the workshop. In the area of ordering he is responsible for:
- The computer technical registering and support of client data,
- writing invoices and reminders of payment (after completion of the contracts) as well as
- for the computer technical price adaptation in the database concerned.
The entering and changing of clients data as well as writing invoices or reminders of payment follows at the usual computer monitor workplace with the aid of the appropriate commercial software. The commercial clerk uses the usual keyboard or mouse for entering and changing data as well as for writing invoices. The work desk without height adjustment and office chair without pelvic support ( figures 1 and 2) do not allow compensation or support for the limited grasp and visual space and the work posture through adjustment possibilities. This leads to problems for the clerk in reaching the keyboard, the mouse, the telephone as well as the printer and looking at the monitor without adopting a forced posture.

Work duties and workplace (desired status):

By using an electric height adjustable work table together with a height adjustable office chair the office clerk can adapt the work surface height (sitting or standing) and the sitting surface height to his body size without great expenditure of energy. The adaptation makes it possible for the clerk to reach the work tools on the desk more easily and he does not have to adopt a forced posture when looking at the monitor (figure 3 and 4). The adjustable office stool with pelvic support additionally stabilises the sitting position and makes it easier for the clerk to sit down, ie. e no longer has to climb onto the office chair. The stabilisation of his body posture follows by means of the pelvic support and the ground contact of the feet (they no longer swing in the air).

Assistive devices used:

work chairs and office chairs


The disabled-friendly workplace layout was supported 100% by the Main Welfare Office.
