Your company’s leadership is responsible to removing gender bias. Treat every employee as equals. The best place to start with this is at the beginning: the interview process for new hires. When interviewing a potential employee, have a man and woman sit in on the interview. Having multiple perspectives can help raise warning flags with a potential candidate should there be one there.
Another tip to eliminate gender bias in your company is to have both men and women in leadership roles. Send the message throughout your company that everyone is of equal status regardless of gender. There are other ways to help with this issue to where employees feel respected and equal.
