I read your leader on the above with interest. It reminded me of the following experience:
I once worked for a large Insurance company. My boss was a manager who came back off holiday to an inbox of several hundred e-mails.
He deleted them all and then sent a mail to everyone in the company along the lines of
“you won’t believe how stupid I’ve been. I’ve come back off holiday and accidentally deleted all the mail in my in-box. If you sent me anything important in the last two weeks, please resend it immediately”
Result: he got 7 (seven) resent e-mails.
I do admit that this is a tactic which can look suspicious if used too often and probably not a good idea if you get lots of important external e-mails. But it was impressive.
