well i am a UPS driver. The problem with this complaint is this. When most of us were hired the weight limit that we were required to lift was 70 lbs and the demensions were different also. Upper level management (people who do not lift a package) decided that they would move the weight limit up to 150 lbs and accept larger packages. I also know that shippers are not putting the correct weight on the packages and shipping them UPS trying to save money. The driver by contract should have had a helper riding with him to handle a package of that size and weight but as i know management does not allow it because it saves them money and gets them a big bonus at the end of the year. I know all to well because of the slipped disk in my back that happened on the job but in the UPS way it was my fault even though I did nothing wrong.
If the car was unlocked they did not break in. They should have got a signature though. If they did not they had to forge your name because the DIAD will not let them complete the stop without a signature.
