You can't be scared of your boss if you want to be successful. I am convinced of this. Now whether the fear is a product of your boss's actions or a result of your own life experience, I don't know. But I do know that irrespective of the reason, you better cut the fear if you want to achieve career success
(And it could be worse, you could work for one of these guys or a dictator)
Here are a few ways to quell the anxiety that surrounds dealing with your boss:
Initiate contact: Find ways to interact with the person in charge. This takes effort and might be uncomfortable, but it's worth it. The higher-ups are not always accessible, but it's up to you to find creative and professional ways to seek them out.
Be prepared: When speaking with your boss you want to make sure you've thought things through from every possible angle. This could require practicing (as silly as it sounds, it works!) and envisioning the different paths a conversation could take.
