The original model of staffing practices described by Winston and Creamer (1997) consisted of five stages: selection, orientation, supervision, professional development, and performance appraisal. Conley (2001) pointed out that employee departure from an organization should be the final step in the cycle of staffing practices. Other studies seem to support this notion. Attrition rates for the profession range from an estimated 39% (Burns, 1982) to 65% (Richmond & Sherman, 1991). Winston and Creamer considered this suggestion and determined that it was well founded and that their model should indeed be revised to include a component they call separation. It seemed appropriate, therefore, to include a discussion of the newest stage of the model in this book on supervising new professionals.
