3. Institute onboarding. Even if you succeed in hiring more women and people of color, you are setting them up for failure without proper onboarding. Engineer Kate Heddleston noticed that for employees starting with the same experience level, again and again men were getting promoted much faster than women. Lack of onboarding was the source of the difference. Valuable information is shared through informal social networks, and people who differ from the majority group (such as women, people of color, trans people, parents, and older employees) will have the most trouble integrating into these networks. Comprehensive onboarding is necessary to make sure that everyone has the information they need to succeed at their jobs.
