Can't speak for all unions but my experience with a couple of unions has been like this. One place had a rule where you (the engineer) can only have 1 CAD drawing request out to the CAD department at a time. And of course the CAD department was backlogged. So in practice it means you're sitting around waiting for the draft to come back for 4 - 6 weeks doing practically nothing.
