Washington just became the latest state to join the social media privacy bandwagon.

On Sunday, a state law banning employers from asking workers for their user names and passwords for their personal social media accounts went into effect. The law was passed unanimously by both the Washington State Senate and the House of Representatives in April and signed into law by Governor Jay Inslee in May. Since 2012, ten other states have passed similar laws governing social media privacy in the workplace: Arkansas, California, Colorado, Illinois, Maryland, Michigan, Nevada, New Mexico, Oregon and Utah.
