Facebook is warning employers about demanding passwords. The social networking site is also threatening legal action over the demands. However, employment lawyers are saying that it’s not illegal to ask. Mind, giving over the password is a breach of Facebook’s terms of service. If job applicants have information in their profile that’s not available publicly that’s verboten to ask at an interview, the interviewer could also be violating employment laws. Of course, check your local laws. In Alberta, British Columbia, and Quebec, such password requests are privacy violations. In Ontario, not so much.
