UPS push thier workforce very hard to work faster. They time them, followow them, and make them memorize 5 pages of safety material 100% or they fail/suspended.
B/C of this micro management system the packages get thrown, tossed and at times packages fall hard to the ground. The employees rush to keep management off thier backs. I actually hate receiving packages from UPS b/c they arrived crushed and beat-up looking. Fed Ex boxes arrive neat clean and unharmed.
I noticed the USPS has become faster, I use them for my shipping needs 95% of the time.
