I'm guessing pammie is referring to when editors give a "9" rating and say something like "lowered due to minor grammatical errors" or something similar. This really doesn't bother me because it's such a small thing. If a shop were disallowed due to errors, I would say a specific reason should be given. If a report "grade" is lowered in a minor way for "minor errors," I think it's fine that editors do not communicate exactly what the errors were. It would be terribly time-consuming to train shoppers so they can write better reports. If the shoppers were employees who completed 10 shops a day, it might be worth it. The time expenditure to train a part-time shopper who works for multiple MSCs would not be worth it. AND, the editors at most MSCs are not paid any better than shoppers are, sometimes they are paid less. A couple of editors have posted that they were paid a flat $5 to edit a report. That's not much money, and, if you have to communicate back and forth with the shopper over minor issues, like "explain my grade," it would be appalling low pay.
My brother tried editing for a while and hated it. He started out all enthusiastic and he sent emails explaining to shoppers what he had to correct, hoping they would see it as a way to improve. Some did and they wanted to email back and forth with him. Others did NOT appreciate it and they emailed asking questions and arguing. What do you say when the shopper emails back and says "No, those 3 sentences do not need commas." ....?
Or, "No, those words were NOT misspelled. You are wrong" or. "Somebody changed my report." Very time-consuming. And over minor errors? The longtime editors laughed at him and told him "Told you, told you!" He very quickly stopped communicating with shoppers with minor issues and only contacted shoppers when he needed more information in order to approve the report or he had to explain why he couldn't approve it. Minor issues, to my mind, do not warrant discussion between shopper and editor. IMHO, it's a waste of the editor's AND the shopper's time.
Minor means minor. pammie is just venting. Me, I can think of much better things to vent about and better places to vent.
