I've recently had a change of supervisor in my office job. Early on, he asked if I could CC him in on every email I send so he could get a feel for what gets sent to whom and how. It seemed like a reasonable request and I obliged.
However, it's now four months later and he still wants to be included. This wouldn't necessarily be an issue, except he often comes to me with questions about progress on things he's already been CC'd in on. It's frustrating to have to keep explaining things like "As I said in the email yesterday, I'm waiting on x" or "Actually, B2 is working on that task, not me." These sorts of questions are almost a daily occurrence.
Not only does it seem like CC'ing him is useless, I believe it might actually be confusing him since he has all his staff (4 of us) do the same thing. And we send quite a lot of emails. Perhaps he simply ends up with far too many emails to read and monitor.
How can I address this with him without obviously criticising his approach to work?
