Just got in from my extended peak season twilight shift. I am a 29 yr old air hub loader responsible for getting packages into containers onto planes so they can get to Louisville. My supervisor is a new supervisor (20 years old) and tonight he wrote me up citing I wasn’t scanning all of the packages at the end of the night. I refused to sign. I guess I took offense to the way this young sup addressed me so we got into a screaming match. Normally I scan all of the packages but when it comes down to crunch time, I skip the scanning to make sure the packages get on the plane on time. The on call package cars come in at 8:30pm and the plane leaves at 9:30pm on the dot. The last container has to be out by 9:15pm, weighed in the scale house and loaded into the plane. I figure it is better to deliver the packages on time to the customer and save the company the cost of refunding the customer for delayed service than to worry about a departure scan showing up on the tracking website. There have been times when I scan all the packages and 9:15pm comes around, containers are pulled and we have Next Day Air packages left on the belt that don’t make the plane. Am I wrong in my thinking? What recourse do I have in this situation besides meeting him in the parking lot?
