"The Contingent Workforce Index provides first-of-its-kind insight around contract labor with a country-level look at how contingent labor markets compare to one another. With this unparalleled perspective, business leaders have the ability to analyze markets based on their unique criteria and objectives, but in a way that simplifies the analysis of that information, allowing them to make better informed decisions about their workforce." Each of the 75 countries in the Index is assessed on 36 market conditions and statistics that influence the state of the contingent workforce. Using a proprietary formula, countries are ranked on their overall environment for contingent workforce engagement and in four key categories: availability of contingent workers, cost of engaging contingent workers, regulation of workforce engagement and contingent workforce productivity. This exclusive analysis provides insights for many aspects of business planning, from expansion of global workforce strategies and MSP programs, to capacity planning and sourcing strategies.
