The future of work

Source: Newsweek Jan 30th, 2006 (Adapted)

Many of the rich world's notions about old age are dying. While the streamlining effects of international competition are focusing attention on the need to create and keep good jobs, those fears will eventually give way to worries about the growing shortage of young workers. One unavoidable solution: putting older people back to work, whether they like it or not. Indeed, cutting-edge European economies like those of Finland and Denmark have already raised their retirement ages, reversing the postwar trend toward ever-earlier retirement. Others are under severe pressure to follow suit, as both the European Commission and the Organization for Economic Cooperation and Development (OECD) have recently warned their members that their future prosperity depends on a growing contribution from the elderly.

This erosion of one of the cornerstones of the good life - relaxed golden years - has not gone unremarked. In the last year, Belgium, Italy and France have all been hit with massive protests against pension reforms that would, among other things, have raised the retirement age.

The global union

Source: Newsweek Special Edition Dec 2005 ? Feb 2006 (Adapted)

What would a global union look like? Think more corporate partnership than class struggle. Today, capital is global and employers are global. Companies, not countries, make the rules. To survive, unions need to find their niche. Global companies are going to need an organization that, in a sense, will manage their labor and protect workers? rights. A global union would set standard practices and codes of conduct - perhaps even minimum wages and work hours.

My critics in the labor movement cringe when I use words like "partnership" and "value added". The reality is that unions need to add value or corporations will ignore us. If we want an equitable stake in the company, we need to define what our goals are. We can't just demand a raise in pay without offering an incentive to the company. We're already far behind multinational corporations in the global game. We made the mistake of transferring the industrial model of unionism of the last country to the 21st. We lost market share: in 1960, one in four workers was in a union; now it's one in 12.
