Yes Really!... From the content of your post you sound like your jealous of the Trainers.....and that you were not selected.... Perhaps not...but that is the way you come across.... Spin it anyway you want...but a Trainer position is never going to be bid according to senority and rightfully so...
A senoir driver bidding onto a Trainer opening does not automatically give that person credibility nor qualifacations....the qualities needed to be successful as a trainer are usually something that cannot be "trained" into someone.... Some people just dont have the personality or other needed traits needed to be effective... I've known several people who desperately wanted a Trainers position that had a lot of senority...but they would have made very poor trainers...the only ones that couldn't see that were themselves... You come across as one of those types judging from your posts....again I may be wrong, as I don't personally know you, however that would be my guess on the matter...
You dont like the idea of a teamster as a trainer......I would bet you'd equally be as resentful if Management conducted the course because they "dont know how to drive a truck so who do think they are to tell me how to drive".... You would only be "happy" if you were the one chosen.... Of course you'll deny that.... It's expected....
Believe me I've heard it all and there is nothing new that you could bring to the table on this matter.....
