Governor Jay Inslee has signed a bill barring employers from asking for a Facebook, Twitter or other social media personal passwords during a job interview or at the workplace.  Washington has become the fifth state this year to sign into law protections of social media passwords at the workplace and job interviews.   The signing wrapped up a session of negotiations between privacy advocates and business lobbyist.   The measure was sponsored by Democrat Senator Steve Hobbs of Lake Stevens. "We don't have to sacrifice our privacy for advances in technology,"  Hobbs said. "As the social media technology advances people are afraid about their privacy, it's good to be ahead of this one."   The bill, however, allows companies to request "content" of employee social media sites during internal investigations, which can be opened if an employer has received a tip that a worker may be leaking information.
