Chief, I think you meant all CARRIERS are poor. (I vehemently disagree) UPS is a Carrier, not a shipper. The shipper is for example what we used to call a mail order business; like MidwayUSA.
In my 43.5 years as a professional UPS driver (now retired), what I saw was a lot of poor packaging.The resulting damage was then blamed on UPS, FedEx, USPS, etc. The people sending out the package in the first place, who were too cheap, lazy, or simply unknowing to sufficiently package items, were most responsible. I’m not saying UPS was never at fault when damages occur, but the vast majority of damages is the result from insufficient packing.
Me personally, I’ve sent a lot of packages UPS over the years.
I use a lot of tape, always double box. I have so much faith in my packaging, and UPS, that I don’t insure my stuff because I know it’s going to get there unharmed.
I knew all the mail carriers, as well as the FedEx drivers in my area. They’re all fine, top notch people. At least they were a couple of years ago.
