I accdiently misloaded 1 package when sorting into the truck. I caught my mistake, but I had to dig the package out to find it. My immediate supervsior yelled at me in front of everyone "You can't make mistakes like that! YOU ARE HOLDING ME UP!" He then got on his radio and said "Mike(me) is being a ". Everyone on a radio and around a radio heard this! I complained to the both of his superiors and said I didn't apreciate being called a In the sitdown, they made him give a backhanded apology where at the end he said he believes I misorted on purpose. I told everyone I felt threatened by him and that I would like a different immediate supervsor. The next day I was informed that from now on I would only be working with the supervisor that called me a because he wants to make me more part of his crew. My question is what can I do to get this guy to back off? I do not want him as my immediate supervisor. Out of the 18 years of load and unloading I have never been written up for misorting. I know a grevance is just going to document this, but should I call that 1-800 help line, talk to HR also? I want to get my message across at all different levels.
