The background for the international research conference "Health Hazards and Challenges in the New Working Life" was the emerging questions concerning the health and social effects of the rapid changes in the labour market leading to increasing long-term unemployment, temporary employment and irregular employment contracts. We knew that other countries have had this development at the labour market for a much longer time than Sweden has and it seemed a good idea to invite interested researchers and practitioners to an international seminar to share the relevant research findings and discuss future research needs. Thus, the first international, interdisciplinary research conference on "Health Hazards and Challenges in the New Working Life" was arranged in Stockholm during the last year of the 2nd millennium but was directed towards the foreseen development during the next millennium. We were very pleased that more than 200 participants came to a cold and dark country just after New Year's Eve, and that it was a truly multidisciplinary setting. It became very obvious that it is necessary for the occupational health and safety research community to reach out to the public health research community as well as to the social and political sciences in order to understand the determinants and to perform comprehensive analyses at several levels in this new labour market situation.
