Would something like the following work (other than sounding a little self-important), or is there another concern?

"Dear McMoo corporate or regional management, I've noticed an operations issue at a McMoo location, which I think probably affects many of your locations. I think the issue might be denying your management accurate data signals, while adversely affecting customer experience and brand, and unnecessarily increasing stress to your workers. [...]"

Sometimes it's worth writing such a letter. If I were in corporate, I'd want that serendipitous letter, about something important I didn't know. (Well, unless my promotion was riding on the worker metrics program I proposed being seen as a success, and my bosses believe more in perfect winning success with the very first shot, than they do in iterative refinement and learning.)

It's more uplifting to write letters of praise for an employee/location. I wrote one recently, to a big national chain. The only tricky part I've found is that I try to imagine corporate rules that might've been violated. For example, I might not want to say, "I told your employee my special-needs child loves your multinational chain ketchup, and the employee immediately fashioned a toy dog out of a dozen ketchup packets, and handed it to my delighted child, all while singing a song from a Disney movie." (In my imagination, that could get the employee written up 6 different ways.)
