Firstly, men make better managers than women, especially when the underlings are female. Regarding staff, naturally it depends on the job, but as a general rule avoid employing a majority of women with a small minority of men, because men need other men to compete with. If the work is task-based, men should excel, whilst women prefer the inter-personal. Women often become confused when forced into the work hierarchy because it is at odds with what comes naturally, their female personal network. Women can mistakenly judge a man's value as an employee by his perceived mate value, which, ultimately, is why we can end up with powerful men who are not fit for office. In a task-oriented environment, such as the workplace, it is only the outcome that matters. As women continue to focus on their social network, they can become confrontational, appear status-obsessed, and resort to 'relational aggression'. See this panel from Moxon (2008). More generally, for an excellent exposition of the way men and women work, see Chapter 9 of the book.
