As the person with the CIO job, you have a lot on your plate. 

You need  to make sure that the company’s networks are kept secure and you need to  make the right decisions about new technology that the company is  considering because of the importance of information technology.  However, you also have to remember that you are a manager and that the  IT department is your responsibility. 

You need to make sure that your department is running as smoothly as possible. What this means for you is that you need to be aware of the effect of rudeness.
