i had one manager who sealed himself in his office and spent all his time running differential equation models he built to monitor his retirement funds ...
we eventually had to nuke him via near Machiavellian means to prevent our entire organization from being disconnected from the Internet because he refused to open his door to sign the necessary RFP bid papers for a new ISP vendor ... [longer version of the story is that i was the leader of the revolt, but the manager thought another guy was the leader, a guy who actually died soon afterwards ... occasionally i’d run into the demoted manager who had quit, and he’d bitterly complain to me about the dead guy who had nuked him ... it was hard for me to keep a straight face] ...
ah, the joys of working for a nonprofit GOCO ... [retired now, thank the lord]
The way we got rid of the real estate gurus is we had their bosses “borrow” the cell phones for a few seconds when the RE guys were in the bathroom.
Needless to say their bosses went totally ballistic—and started monitoring the RE guys every minute.
In both cases it only took a day or two before they were fired.
In both cases they did fine—they sold their real estate holdings and moved out of state.
Win win.
