Tough spot..
Couple of thoughts.
- I do not believe our e-mail systems copies bcc’s on replies unless you do a “Reply All.” Not certain. I rarely bcc.
- Might try read receipts to see if that gets you any more info.
Otherwise, I would only use e-mail if you absolutely have to and certainly would not editorialize at all.
As I’m fond of saying: “Go darken his doorway” and provide opinions to his questions in person if opinion is needed.
Good advice. It’s a tradeoff between BCC and giving a 5 minute verbal opinion that turns into a 2 hour meeting. My work doesn’t go away, he just makes it all take so much longer.
