Bah!
There are about three people in my enterprise of over 500 who wear their badge as demanded in the Official Memo Re Badges: all the time and above the waist.
The managers typically wear them clipped to a belt (against policy) and the rest, including 100% of the consultants, never display them.
Not only os this a security nightmare, it is fucking rude. How in hell am I supposed to know your name when I need to ask you a question in a meeting?
But now the SAs are insisting on deploying sudo "for security". On some servers. Only for certain staff. And not the SAs.
HASP * in action.
* Half-Arsed Security Procedures. Not intended as anything but a sardonic kick in the nuts from them-wot-can to Teh Luzerz.
