Much research has been done on the difference between men and women in the workplace. Men negotiate their salaries; women take what they’re offered. Men talk up their achievements; women downplay theirs. Men ask for what they want; women wait to be invited.
Add in the fact that most senior executives are men who tend to promote other men, a.k.a. “the old boy network,” and it’s no surprise that women make up 47 percent of the US labor force but only 4 percent of Fortune 500 chief executives.
