Working closely with anyone gives you useful insight into her performance. This is especially true of your boss, who you likely see in a variety of settings: client meetings, presentations, one-on-ones, negotiations, etc. But even if that insight could be helpful to your boss, is it your place to share it with her? Could you be putting your job or your relationship at risk by telling her what you see or by giving her frank feedback? Giving your boss feedback, commonly called upward feedback, can be a tricky process to master. However, if offered correctly and thoughtfully, your insight can not only help your boss but also improve your working relationship.
