Usage Guidance

  • The number of departed permanent employees should only include employees departing the organization voluntarily. Organizations can refer to Departed Permanent Employees: Voluntary (OI8431) for additional information on voluntary departures.
  • For employees departing the organization involuntarily, organizations can use the metrics Departed Permanent Employees: Involuntary (OI7225) and Employee Involuntary Turnover Rate (OI3989).
  • The average number of permanent employees can be calculated a number of ways. One example for organizations reporting on a yearly basis is to calculate the average number of permanent employees on a monthly basis.
  • Organizations are also encouraged to report this metric in conjunction with Average Employee Tenure (OI2248).
