Use your knowledge of forecasting internal labor supplies to select the correct labels for this image. An estimation of Internal Labor Supply is given by an equation that reads "Current Staffing Level minus Projected Outflows This Year plus Projected inflows This Year equals Internal Supply for Next Year." A flowchart shows that Staffing Level tracked influences Sources of inflows and Sources of outflows. The Sources of inflows determines Current Staffing Level that in turn determines Source of Outflows. Staffing level is tracked using replacement charts; succession planning. The sources of inflows are external hires, internal transfers, promotions, recalls, and demotions. The sources of outflows are promotions, turnovers, termination, demotions, retirements, deaths, and layoffs. A. B. C
