This is an overly narrow view of "use Tor". In any corporate
environment, including customer support settings, it could be
important to protect searches of public information (including perhaps
especially competitor information) from competitors and possible
network observers. Maybe _you_ would have no reason to use Tor there,
but your company would have a reason for you to use Tor.

In an inadequately configured environment, perhaps. But corporate
investigators and law enforcement officers use Tor all the time to
investigate crime online and could have to do so unofficially if no
adequate sanctioned solution were available. Even in an inflexible
setting that tension is unnecessary, however. We specifically designed
for multiple usage scenarios including one where your use is subject
to local monitoring but still is protected once leaving the local
network. The case here is described under Proxy-and-OR-at-Firewall
Access in "Onion Routing Access Configurations".
