None of us are perfect: all of us will from time to time fail to live up to our very high standards. What matters isn’t having a perfect track record, but owning up to your mistakes and committing to a clear and persistent effort to improve.
If you are approached as having (consciously or otherwise) acted in a way that might make your teammates feel unwelcome, listen with an open mind and avoid becoming defensive. Remember that if someone offers you feedback, it likely took a great deal of courage for them to do so. The best way to respect that courage is to acknowledge your mistake, apologize, and move on — with a renewed commitment to do better.
That said, repeated or severe violations of this code can and will be addressed by the people and culture team, and can lead to disciplinary actions, including termination.
