Hmm well I chose to learn all the destinations and to learn the purge on my own, no one told me I do it I thought I'd be appreciated and instead I'm being tortured for my good efforts and hard work. I understand we are supposed to listen but can you not fathom from a moral standpoint how abused and ed up this makes me feel? I don't get how good work is rewarded with more work and threats of being fired when the workers who hardly load their trailers properly and don't care to help anyone else are left alone and me the one who's doing a good job is at risk for dismissal. This is absurd.
You asked if you could get fired for not doing were told. We told you yes you need to do what your told unless it unsafe.
Nothing else matters it doesn't matter what jobs you know or how you learned them. You need to do what your told to do ( Work as Directed and grieve later )
Some how you think you don't need to follow directs for reason that make no sense except to you ...
