Blogging yourself out of a job

With my job at the directv call center, I access all kinds of customer account infomation daily including addresses and credit card information. This sort of infomation is very confidental as well as other directv information that is to be kept inside the company. There are many pieces of information that could easily hurt our company or our customers if they were placed in the wrong hands. I think that people should be very cautious when discussing their company or any company business.
