In 2010 15.2% of the work force in the Netherlands works with a computer at another location than at the office or at the clients' location. 27% of the Dutch working population is not satisfied about the possibility to work at home and 18% is not satisfied on the possibility to plan your own working time.

In implementing new ways of work these issues need attention.
