Alex knew things nobody else did.
He thought of it as job security.
Who would fire the guy who was the only one who knew how to do things?
“Write it down,” demanded his boss.
But Alex ignored him.
“Are you going to fire me?” he said. “In fact, give me a raise, or I quit.”
When Alex went on vacation, things would grind to a halt.
Alex’s boss decided to harass Alex, flooding his phone and text messages.
Until Alex suddenly died of a stroke.
“It was the knowledge,” said Alex’s boss. “It wanted out, and it killed him.”
