I will be honest. In my career, I have tended to promote more men than women. I have even generally given men higher salaries. Why? Am I sexist? Do men do a better job? The answer is a resounding no to both.
Actually, it is mostly women's fault. They simply don't ask for raises or promotions as often as men do.
I'm sure the author, Shaun Rein, is a bright fellow but logic is not his strong point. He's not sexist he is just biased towards men, go figure Shaun.
Good managers seek out the best talent, cultivate and reward it accordingly. Poor managers reward the people who whinge and self-promote the most. Mr Rein fits into the latter category. His article reveals more about his own shortcomings as a manager, then they do about women.
