I dunno. It's now SOP, when a person leaves under any circumstances, including routine retirement, for his last act to be turning in his ID at HR. Someone from HR then escorts him out of the building. It's a little graceless but there's a lot of information encoded on the chips on modern government ID's, so they're more careful than they used to be.
I was a Senior VP at a place. I wasn’t even allowed to clean out my desk. I turned in my laptop at the Corporate office, and was told that anything left in my office would be delivered to me.
It was amicable. And I had seen it before. But damn...it kind of pissed me off.
