I switched to FEDEX a year ago. My concern was each driver is an independent contractor. How would this effect the overall quality of service if you have to deal with different contracted drivers when shipping to different areas. But service has been very good and aside from the occasional damage you can get with any package being tossed and handle by multiple people, i have not seen any regional issues with drivers. This Saturday and Sunday delivery only applies to residential locations, not commercial. I believe.
