In a Harvard Business Review essay, Robert Sutton urged companies to implement no asshole rules: to refuse to hire people – even superstars – who are known jerks, and when insiders had episodes in which they belittled and bullied others – especially those with less power – they should be called on immediately. Sutton pointed out that firms that applied such rules would likely enjoy less turnover and absenteeism, lower health care costs, and reduced litigation risks. He also pointed out that some companies already have such rules, and such rules do help them maintain more civilized workplaces.
