I thought (I read it here...) the only DQ that a person could grieve when qualifying was not being on the same route for their qualification period.
I would suggest, if you are still qualifying and a supe tells you to follow Orion, follow it. Break trace only for business and commits, then go right back to trace. If a supe says something the next day, respond, "You told me to follow Orion. I did. What would you suggest??" and then do not say anything, do not suggest an answer, be silent and wait for a reply. Have your shop steward with you for this conversation.
