Directions: These tables summarize employee availability to handle call taking and dispatch functions in the center. This is similar to a shift relief factor but it is based on hours. This adjustment is appropriate for coverage and volume-influenced positions only. Calculate Net Available Work Hours (NAWH) using average allocated time or average actual time for each category. Use the "Other" column to adjust for time off that may be unique to your center, Round all calculations to the nearest whole number. The result is the average availability for each person in that position.
