Pension funds have come to play an increasingly important role within the new economy. According to Statistics Canada, in 2006, trusteed pension funds in Canada had $836 billion of assets and represented the savings of 4.6 million Canadian workers. Pensions at Work is a unique collection of papers that uses a labour perspective to deal with the socially responsible investment of pension funds. Featuring leading Canadian and international scholars, it builds on existing scholarship on socially responsible investment and on the growing interest of the Canadian labour movement in joint trusteeship. What is unique about this collection is that it synthesizes three distinct themes - socially responsible investment, pension funds, and labour studies. The contributors address an array of critical issues such as gaps in the education of union trustees of pension funds, the impact of human capital criteria on shareholder returns, the influence of corporate engagement upon corporate performance, and the nature of public-private partnerships (PPPs). Although the essays in Pensions at Work all address the nexus between socially responsible investment, pension funds, and unions, each looks at a particular manifestation of that relationship through a different disciplinary lens. This collection moves the discussion to pension funds in which union representatives are also trustees, a relatively new approach that will be of great interest to institutional investors, the labour movement, and instructors in labour studies programs.
