No one likes confrontation, but negative feedback is important for growth, particularly in a professional setting. Much scholarship has been done in the realm of feedback, and despite nuance, the core lesson is always the same: It’s better to be tough but honest than nice but fake. Engaging in these difficult situations is uncomfortable, but there are ways to make it easier. For one, find or create the right context. If you must tell someone something they aren’t going to like, it’s best to prepare them in advance rather than ambushing them. Also, understanding their schedule and personal circumstances can help in establishing the context of your conversation. Find a format that works for both of you. While it might be easier for you to email them with negative feedback, consider how it would feel to be on the receiving end in that situation. Maybe it’s better to have a phone call so they can ask questions. Also, keep in mind that you might be wrong. Disagreements are caused by various factors, and until you have a discussion, you’re only seeing your side of the story. No matter how convinced you are that you’re right, there’s always the possibility that there is information you’re unaware of.
