Back when the earth was cooling and I was at JPMorgan, every member of the trading floor staff who left for any reason, was monitored by security while they took personal items only from their desk, and then escorted to the building door where their key-card was collected.
The very first time I saw it, it looked like a perp walk, but there was no shame in it since it happened to everyone.
Eventually you didn't even notice the security.
I left one job (in sales) in order to work for our competition. On my way up to the VP's office, I stopped by the security desk.
"I'll need your help now, Frank."
"Today's the day?"
"Yup."
One minute later, the VP said, "Hold on a minute while I call . . . ." I interrupted and said, "I've got him right outside the door." No problems.
