⟩ Why should you keep the results of your performance review to yourself?
Usually, performance reviews are the sort of thing you will want to keep to yourself about. Like your salary, this type of information can lead to jealousy and hurt feelings if you're too open about it. Do not bring up the results of your review in casual conversations. Instead, only consider discussing your review with your family, your friends outside of work, and select coworkers you have a great amount of trust in.
☛ If, for some reason, you do need to discuss your results with others, be tactful. Do not brag or joke about your results, you will never know how they will compare to your fellow coworkers'.
