As mentioned before, always assume good intentions, people are helping you. Always thank a person for sharing feedback with you, even when it’s hard to digest.
Whether you're the one giving or receiving it, feedback is an invaluable tool that enables you to see your performance from an outside perspective. Hold off your gut feeling and consider the feedback. Have an open mind and dare to learn.
Ask to elaborate
One of the most important things you can learn from feedback is the inadvertent signals you may be sending in the workplace. However, as you know now feedback in an office environment is based on observations and perceptions, so misperceptions in the workplace will exist.
Make sure you understand the point of what the other is saying. If feedback is not clear, start a conversation and ask for clarification and/ or examples.
After you thanked your peers, keep them in the loop about small changes in your behavior based on their feedback. Not only will they appreciate that you acted on their feedback, but it will also reassure people that their input will be well received, encouraging them to continue to be open and provide useful contributions in the future.
Tangible change will give them a reason to keep sharing feedback and will add credibility to the feedback cycle.
