ABSTRACT
In almost all the classic ergonomic textbooks of the 1980s and 1990s, a description of an optimal computer working posture is presented, with emphasis on adjustments of the office chair and the position of the computer screen and keyboard. The set-up of a computer workstation could be seen in rooms occupied by one person (what is called a cell-office) or two or three people (a shared-room office). Besides cell-offices, also open plan environments were created, where people with comparable jobs were put together, sometimes divided by screens, walls and plants to create differentiation and privacy. The revolutionary increase in mobile technologies and communication media, created an increase in open plan offices. The open layout is often combined with a flexible work organisation, a work practice that allows employees a certain amount of flexibility in respect of time, place and duration of work.
