First on the docket will be the guy in Toronto who, if I haven’t responded to his email promptly, will WHINE TO MY BOSS that I’m not working. He does this all the time, as recently as yesterday – an email sent at 9am hadn’t been answered by noon (because I was BUSY), so he escalated to my boss TWICE to complain that I hadn’t gotten back to him. Seriously? Do you not have enough work to do that you sit around hitting F9 to see if people have replied to your messages? Do you have a stopwatch? This is rage-inducing and pathetic. Perhaps I will go whine to HIS boss that he is being a bully.
Today I am covered up in honour of George and the CBC!

There’s a time and a place for email and, if your question MUST be answered in less than 3 hours, then email isn’t the appropriate communication tool.
i.e. he’s an ass (which you already knew).
I’d be tempted to LET him whine to your boss. As long as you manage your boss correctly and you have valid reasons for not dropping everything to prioritize the Toronto Turnip then there will come a point where a good boss will get sick of this idiot’s attempts to manage staff who aren’t his to manage and slap the guy down.
