All you can do is try to convince all involved of the right thing to do, you can't force them, those that are not doing what's right will only hurt those involved in that route. I have given up on most of the others in my office, due to this dragging out so long it's hard to keep them focused, it's their pay its effecting. As for my route I've pounded into my RCA so much that I think my route will be OK!
This brings to mind an argument that I had with a postmaster when I was an RCA. We got into it when we were having a count one year, I was working harder and was more informed than the Regular Carriers in trying to get all I could for the three routes I worked on at the time. I would battle tooth and nail for everything throughout the process. So one day the PM got really heated and said to me "Why are you battling so much for these few minutes here and there, the Regular Carriers are accepting things the way they are?" My response was "Because it my paycheck too, it actually affect my income more adversely because if the evaluation drops to much I have more to lose." Well needless to say of the two K routes and one J route that I had before the count only one remained a K the other two dropped one to a J and the other to an H. I went from working 3 days on week and 2 the second to a 2 and 1 situation. You should have heard all the bitching from those Regular Carriers of how the system sucked and their evaluation should be higher, I just looked at them and laughed! By the way I transferred out of there a short time after.
So the moral of the story is anybody involved in running a route needs to take ownership of that route and do what's right, it's not a race to see how quick you can half azz a route. If you don't follow all the guidelines, procedures and things like scanning & line of travel it will all come back to bite you in the azz.
