Information on employee tenure—the length of time that workers have been with their current employer—may not grab headlines or get mentioned in social media as frequently as other measures of the labor market, such as employment growth, the unemployment rate, or earnings trends. Nevertheless, measures of employee tenure can be useful in understanding long-term trends in the labor market. A number of factors can affect the median tenure of workers, including changes in the age profile among workers, as well as changes in the number of hires and separations. This Spotlight on Statistics examines trends in employee tenure by various demographic and socioeconomic characteristics, and highlights some of the factors that affect these trends for the period from 1996 to 2012.
