Employee Value

From Cy Wakeman's book "No Ego: How Leaders Can Cut the Cost of Workplace Drama, End Entitlement, and Drive Big Results"

According to Wakeman and her theory of Realty Based Leadership, the formula to measure the value of an employee is:

Employee Value = CP + FP - (3 x EEx)

Where CP = Current Performance (How am I doing today?)
and 
FP = Future Potential (How am I preparing for whats next?)
and
EEX = Emotional Expense (Amount of emotional waste and drama.)
