I always tell my students to be careful what they post online. In today's global economy, it is not uncommon to walk into a job interview and be confronted with a question or two about a person's social media practice. Even when one thinks his or her site is set to private, many employers are able to view a prospective employee's information. Now employers want usernames and passwords to Facebook accounts during interviews. Interviewees are faced with the dilemma of divulging this information or risk not being hired. What does this mean? Is this legal? Some employers have gone so far as to even ask new hires to add them to their accounts. I feel that my work is my work and my play is my play. So long as I am legal and moral then everything is fine. I try to set the example in every aspect of my life. I do see this policy being widespread. The younger generation needs to take heed.
