About 12 percent of workers have fantasized about killing their bosses, according to a recent survey conducted in the United Kingdom by consulting company Expert Market.
Rates varied by industry. Construction workers were at the top, with 22 percent admitting that, at some point, they'd had bloodthirsty thoughts about supervisors.
The survey responses shouldn't be taken too literally, said Rachel Frieder, an assistant professor of management at Old Dominion University's Strome College of Business.
"We've probably all joked, 'He makes me so mad, I could kill him,' " Frieder said. "But it's just an expression. We'd never act on it."
Even then, such thoughts are likely reserved for the worst managers.
Some tension is inevitable. Workers spend much of their day on the clock, earning paychecks that are vital to their family's stability. Managers can stir emotions that can get out of whack.
One in five workers surveyed said they'd give up a pay raise in exchange for having their boss fired.
Frieder said employees want different qualities in a leader. Some like plenty of interaction. Others prefer the boss at a distance.
