One stumbling block is that many people believe that the workplace is largely a meritocracy, which means we look at individuals, not groups, and determine that differences in outcomes must be based on merit, not gender. Men at the top are often unaware of the benefits they enjoy 'simply because they're men, and this can make them blind to the disadvantages associated with being a woman. Women lower down also believe that men at the top are entitled to be there, so they try to play by the rules and work harder to advance rather than raise questions or voice concerns about the possibility of bias. As a result, everyone becomes complicit in perpetuating an unjust system. (p.151)
