The "Purple Promise" is a joke, and it is widely ridiculed at FedEx because it's meaningless. It's ironic, but actually going the extra mile to satisfy the customer could get you disciplined or even fired. For example, cutting your lunch short to re-attempt a badly needed pkg could get you an OLCC. How about re-delivering an address correction out of your route area that caused you to get a couple minutes of OT? Probably another OLCC.
There isn't much incentive to give any extra effort these days, and actually thinking for yourself in order to provide an outstanding customer experience is taboo. Management has pretty much taken any discretionary decision-making out of the courier job, and employees are slowly but surely figuring out that your reward for doing an excellent job will be additional work with no monetary acknowledgement.
Even if Purple Promise goals are reached, the payouts are a joke. Like a previous poster said, the payouts this past week were around $25.00 for PT and in the $50.00 range for FT, which works out to around a quarter a day for going above and beyond for Fred. In the past, excellence was rewarded at FedEx. Now, mediocrity is the norm, and superior service is just lip service. In short, FedEx is still living off of a reputation for past excellence it no longer deserves.
