The retail industry in the United States has, historically, had a higher than average turnover rate. Hourly store employees have the highest turnover rate at 65%, according to a survey from the Hay Group division of Korn Ferry. Considering these lower retention rates, hiring or promoting an employee to supervisor can be a frustrating, slow process for employers. However, if you hire supervisors with the right skill set, you may be able to drastically reduce these turnover rates, for both your supervisors and the employees they oversee.
