Business leaders have to keep their egos in check if they want to create cultures that encourage workers to be transparent and tell the truth, writes Dana Theus. A recent survey found that four out of five workers had been penalized for telling the truth, with 70% blaming their bosses' swollen egos. So what? you ask. Surveyed companies whose employees were afraid to speak their minds had 5.8% lower shareholder returns than those where people felt safe to share their thoughts.
