You should have worked as directed. In our district; you must work as directed unless that direction is a safety issue. Do what your sup says, document it, and then question it to their superior. Refusing to work as directed will get you discharged. I have been instructed to DR businesses on a 3 day ride in their mail slots and I did. I then brought it up with the superiors and it was corrected.
Bottom line Work as Directed
You cant get fired for refusing to work as directed if the directions you are being given are contradictory and mutually exclusive of
other directions you have been given. You are being told to do two completely
opposite things, so no matter
what choice you make it will be the wrong one. I would file an Art 37 grievance for over-supervision and coercion, thereby putting them in a position where they will be forced to explain and defend their instructions in an open forum. Whats going on here is actually quite simple; missed packages look bad on the report, your management team doesnt
want to look bad on the report, and they are instructing you to falsify your delivery records so that they
wont look bad on the report. If the Loss Prevention dogs ever showed up and started sniffing around, my guess is that your management team would immediately suffer a convenient "loss of memory" in regards to the instructions they gave you for incorrectly sheeting those packages, leaving
you to have to explain why you failed to follow the DIAD training that you had been given.
