A new blog - www.pasecrets.com - offers them the chance to share tales of management incompetence, expenses fiddling and demands beyond the call of duty.
However, postings are anonymous, so it falls to adland's deductive reasoning to establish which bosses the PAs are referring to.
Who could the delightfully handled Scum be writing about when he or she says: "My boss is number two in command and he is clueless. He often asks me for an opinion - and that opinion more often than not ends up being his official line"?
Then there's Exec, who writes: "Just saw my boss pitch the same idea to three different clients in a row. Interesting to see what happens when two of them take it on."
And surely someone knows who SecretChick is talking about when she tells of the boss who made his staff stump up £55 each for a lunch, then pocketed the receipt and put it through on his expenses? E-mail firstname.lastname@example.org to name and shame.
