Whether it's taking on more responsibilities or staying late in the office, many employees will go above and beyond to try to get a pay rise. But now a study suggests that if you're not good looking, your efforts may be futile. Researchers from the Institute for Operations Research and the Management Sciences in Baltimore have uncovered a'striking' link between physical attractiveness and career success. In their study, the team analysed the careers of more than 40,000 graduates who had completed MBAs. They found attractive respondents earned up to 11 per cent more than their colleagues who were seen as less good looking.
