The current research literature on voluntary employee turnover exhibits at least four shortcomings: low predictive validity, excessive exuberance with predictors, low rigor, and little relevance. Existing theories of voluntary employee turnover research are under specified, as none contains the full range of variables originally hypothesized by March and Simon as contributing to individual employees' decisions to quit their jobs. March and Simon (1958) contributed to the current state of affairs by making at least one assumption that subsequent results do not support. Subsequent efforts to expand theory and to detect and integrate new explanatory constructs have led to a much deeper understanding of the same small portion of turnover variance explained in employee decisions to quit. Deficiencies in current approaches and what a nondeficient model of voluntary employee turnover might look like are described. Directions for future voluntary turnover research are identified, as are past trends that need to be discontinued.
