Calculating Gross Staffing Needs
Gross staffing needs represent the total personnel required, encompassing operational and reserve needs.
- Formula: Operational staff needs + Reserve staff needs
Example Calculation: A retailer prepares for the holiday season. Historical data shows about 1,000 customers per hour need assistance. With one employee serving 100 customers hourly and a 20% reserve added for absences:
Operational staff need: 1,000 ÷ 100 = 10 employees
Reserve staff need: 10 × 0.2 = 2 employees
Gross staff need: 10 + 2 = 12 employees
Calculating Net Staffing Needs
Net staffing needs consider employee turnover and current workforce levels.
- Formula: Gross Staffing Need – Current Workforce
