Labour market flexibility is the much touted recipe for reducing unemp
loyment, the major problem of the Finnish economy today. In spite of a
fairly wide agreement on the need for reforms in this direction littl
e is done. Even minor reform proposals tend to end up in insurmountabl
e disputes. The reason seems to be a deeply rooted fear in trade union
s of loosing the foothold if the present system is allowed to change e
ven marginally. In this paper I outline the major economic changes in
the world which call for a revision of the role of trade unions. On th
e basis of modern economic theory I explain why trade unions continue
to be important, albeit in a different form than presently. I argue th
at actively adapting to these changes should prove much more beneficia
l in the long than stubbornly trying to defend institutions which have
outlasted their time.
