The days of company heads firing scads of entry-level employees to save a few dimes at the end of the day are over. Or at least they should be if companies with large workforces want to attain maximum profitability, says McGill University’s Jody Heymann. “There are companies around the world that have recognized the value of entry-level employees and are making it an enormous competitive advantage and a central piece of their competitive strategy,” said Heymann, Canada Research Chair in Global Health and Social Policy and founding director of the McGill Institute for Health and Social Policy. Her study, entitled Profit at the Bottom of the Ladder, was published in the Harvard Business Review. It was co-authored with research assistant Magda Barrera.
