While it can be said that the use of collective labour agreements has greatly expanded during the last decade, it is hard to deny that their power to protect employees has diminished considerably and continues to weaken. An understanding of the factors that have contributed to this fundamental change in economic and social conditions is of crucial significance if we are to preserve an equitable balance in the employer-employee relationship. The eleven papers reprinted here were originally presented at the 16th Congress of the International Academy of Comparative Law, held in Brisbane in July 2002. Each paper is organized around the following considerations for the particular country in question: factors determining the role of collective agreements; factors determining the regulatory power of collective agreements toward the employment contract; factors limiting the regulatory power of collective agreements; degree of fredom of the parties to shape the employment contract; and future prospects for collective agreements as a means of regulating the employment contract. Underlying issues of decentralization, minimum standards, decreasing unionization, unemployment, and the growing individualization of the employment contract are addressed by all the authors. The countries covered are Australia, Belgium, Canada (Quebec), Greece, Italy, Japan, The Netherlands, Poland, South Africa and Switzerland.
