Don’t let your emotions overpower your reaction

Rather than lashing out or letting your emotions get the better of you, pause before acting. It will help to detach emotionally.

If you feel safe enough to approach your colleague, respectfully initiate a candid discussion with the bully. If the bully responds, listen instead of getting defensive. You may discover that there is room for reconciliation. However, if the bullying continues, it may be good to approach HR or your manager.
