It can be awkward to give constructive feedback to someone who’s not in the same room as you, but if you manage remote employees, you’ll have to do it. Set up a video conference, and be sure to position your camera at eye level; any lower will make it seem as though you’re looming above them. Maintain natural eye contact, and keep your body language open and relaxed. Start your conversation with the usual small talk, but make an extra effort to be warm. Express your appreciation for their work, if appropriate. Since your virtual employee may not have the regular opportunity to read your tone or body language, establishing this mutual trust and reassurance will help your message become more palatable. Keep in mind, though, that you shouldn’t couch your constructive comments in too much positivity, or else your feedback may get lost. Just say enough to confirm to your employee that you’re on their side.
