New Jersey's Social Media Privacy Law took effect yesterday, prohibiting employers in the state from requiring applicants or employees to disclose their personal social media usernames and passwords or to provide access to their personal social media accounts.

The law also has a strong anti-retaliation provision to prevent employers from pressuring employees or applicants into waiving their privacy rights.

The measure, however, does not restrict employers from viewing publicly available social media pages of either employees or applicants.
