Women often tell me they prefer to work with male bosses than for other women. While I don't think one gender make better managers than the other, I did come across some research from the US journal Psychological Science and summarised in The Telegraph which goes some way to explaining why some women may have this preference. "The research team from Emmanuel College in Boston asked male and female college students to rate their room-mates under different scenarios. When asked to judge how they would rate their room-mates if they carried out a single fictional act of negative behaviour, after they had been otherwise completely trustworthy, women were far more likely to be critical of them. Men, on the other hand, were much more tolerant. Women were also more likely to switch to a new room-mate than men were, and were much quicker to form negative impressions of the other woman. The authors, led by associate professor of psychology Joyce Benenson, concluded that women were harsher on their peers because they expected more from their same-sex relationships than men did. While the study did not take place in the workplace itself, it would appear to back up previous surveys that have found women prefer to work for a male boss." Sound familiar? We can be our own worst enemies.
