If you’re an individual contributor, without a position of formal authority, you should assess your strengths, skills and gaps related to DEI advocacy, that is, your ability to support and promote diverse people.
How willing are you to speak up when you witness a microaggression, for example? Do you share your thoughts in meetings and encourage others to do the same? Inventory your biases, both conscious and unconscious.
Ask colleagues and your manager to help you understand the biases and blind spots you might have trouble recognizing. Ask them whether they think you show courage in supporting inclusion in meetings or elsewhere.
