You use an antiquated term to refer to the management employees of UPS as “Partners”. The partnership (as it was) has been dead for quite some time; I believe that most would agree that its funeral was on 11/10/1999 (the day UPS went public), which was (I believe) was also the date when MIP was also uncoupled from profits; and the amazing surge in the compensation at the C-level (CEO, COO CFO) began.
Now as to MIP, there are I believe six elements today that are looked at for MIP in 2011, not just profitability:
Balanced volume growth
Growth in revenue per piece
Growth in consolidated revenue
Growth in consolidated adjusted earnings per share (EPS)
Positive operating leverage
End-to-end service
And of course, the goals for each measure are set by the “compensation committee”.
Now at the end of the last quarter, I believe that three elements were at or above goal / target; and three elements were below goal / target; or 50% effective.
So, if the results trend held (only 50% to plan) ~ you would have a .5 month (for a one unit supervisor) and 1.0 month (for a two unit manager) since you are 50% to plan. To pay anything else implies that the measure is subjective.
