How can a memebr of staff in a company argue with the manager
about the manager's decisions or performance?
It is IMO the *obligation* of a professional to call his manager on
wrong decisions or performance.
I've advocated the equivalent of the following opinion before
(http://www.ietf.org/mail-archive/web/ietf/current/msg77479.html), but
in the current context it bears repeating: Here in the IETF we accept
that low-status people may argue regarding technical matters, but
reserve for high-status people having opinions about our procedures.
