The purpose of this paper is to analyse some recent developments in tele working, considered as flexible work forms linked to the widespread use of information and communication technology (ICT). First of all we draw an overview of emerging and declining forms of telework, referring to recent results of an international survey carried out for the European Commission. This overview highlights that the various teleworking practices can no longer be analysed from the single point of view of �working at a distance'. The second section analyses them in a more general framework: the expansion of flexible work organisation and �atypical� work forms, which characterise employment in the information society. These aspects will be commented on in the light of some results of a European socio-economic research project (FLEXCOT), allowing us to pinpoint the role of ICT in these trends. In conclusion, the paper addresses some challenges for industrial relations and collective bargaining.
