i know of couple people who have blown trailers and air retain trailers who have received no repercussions for doing so. i have recently been blamed for missing a 49 piece air bag that supposedly i missed, my pt sup missed, another pt sup missed, and a final walk off with 17 other pt sups missed and have been sat down and told i will not be recommended to receive my mip for 2013. although i received a 2.5% raise this year for being i guess a "horrible supervisor" i do know of many instances where other supervisors have blown loads do to blantlently not checking every trailer when performing yard check or walk offs. i also know that the consequences were not as severe as mine. they did not lose their mip. instead all they had to do was to give a write up as to what happened. maybe if i was white that would be the worse that would happen to me.
