How are you getting you work done today? How about tomorrow? If contractors are playing an increasing part of that equation, you are not alone. Research tells us that between 25 to 30% of today's workforce are workers under contract--hired for the short-term to augment an existing team or to supply specials skills necessary for a particular project. Some contractors serve as independent contributors, working side by side with a team or independently; some serve as interim executives, filling key leadership roles for a defined but not permanent period of time. And experts are predicting that this contingent workforce will grow to 40 to 45 percent within the next ten years, according to CNN Money.
