Technology is the momma of the modern workplace, its creator, from the Industrial Revolution to the blessedly short-lived dot.com era. It has re-shaped work, making it cleaner, more mobile and flexible, safer -- but much less secure. Jobs now change as often as the market fluctuates, as mergers and takeovers shift the landscape, as the market bumps up and down, as marketing tracks our desires and dislikes, needs and whims. Technology makes it possible for companies to shift jobs all over the world, and redefine themselves in weeks and months. Qwest tossed 4,000 workers two weeks ago. The very idea of job security seems a casualty of the tech-driven global economy, with its continuous down-sizing, changing ownership and management goals, lateral strategies and evolving needs. Now we add terrorist attacks and a recession. The new corporate work ethic is change -- measured, defined and executed by corporate hierarchies. Do they owe anything to the people they dump?
