Since they agreed to keep most of the personnel of the old companys, I guess it will be evolution, not revolution, as far as retraining, etc. RPS did things differently, and there is probably resistance to change and growing pains. I wonder if RPS was Teamsters? Fedex is non-union.
I have been please with Fedex Ground in this area (Baltimore/Washington DC). There is an industrial park a mile behind my office which has truck depots and direct drop-offs/pickup for Fedex, UPS, as well as the regional sorting center for the Post Office where big packages can be handled, so I have lots of choices near by.
