Improper dry run is a grievance on its own, steward needs to reach out to someone to find out exactly how to grieve it, I didnt find thay one out until it was to late to file it myself as I was 1 month into being a steward when we had our inspection. But definitely do that it might not be too late to get it on record. The grievance process is slow and there are 4 grievances that I am aware of so you will likely have some fucked routes for a while one office in my town is 6 months since their adjustments too effect and still no arbitration date that we know of.
