Most bosses live in fear that their best employees will leave, so it might seem to be a bad idea to encourage your stars to consider outside offers. But in fact, it sends employees a clear signal that you really care about their learning and development. Openness allows for an honest conversation between you and each employee about their future career path. If they do decide to leave, they’ll be more likely to recommend you as a great boss, and also more likely to return at some future point.
