Criticizing your superior is a tricky thing. While good superiors mostly want to know the views of their subordinates, particular skills are necessary to express the criticism. Cbsnews.com advises how to criticize correctly and, thus, do not damage the relationship with your boss.
Ask clarifying questions
Questions can help you naturally show your boss that his suggestions may not be entirely correct. Do not emphasize your own dissent or unwillingness to do something, point to imperfections of the proposed process.
Choose the right place and time
Choose a place and time that you think will best suit your supervisor. Watch carefully the nonverbal signal that could mean that your boss is currently frustrated, insecure, nervous or overwhelmed by work. In such a case, do not give your feedback. When a good time comes, talk together privately. Never criticize your boss publicly.
Show the benefits of your solution
If you want to change the way your boss does something, show him what benefits will your suggestion have for him. Tell him that you are aware of how the given project is important for him and that your ideas can help him reach better results.
Communicate early and often
Regularly talk with your boss to create professional relationship based on mutual respect. He will then accept your criticism much easier.
Ask if you can give your feedback
If you do not have an informal relationship with your boss, always politely ask in advance. Try a question such as: "Would you mind if I share my perspective of the matter with you?"
