My be helpful to note that FedEx uses two VASTLY different groups of employees... the FedEx air guys with the classic colors and logo are decent and solid, the FedEx Ground guys sporting the bright green/purple have lousy jobs, get paid poorly and get treated similarly and their service (and their equipment and the quality of their driving) reflects it. And USPS is being similarly contracted out and their final delivery service (in some places) reflects it as well.
