Ariz. bill: Workers' online info should be private

As social networking sites have become more popular, managers are increasingly reviewing publicly available Facebook profiles, Twitter accounts and other sites to learn more about job candidates and employees. But some companies and government agencies are taking it further and demanding applicants and employees give up their usernames and passwords.

Arizona is one of dozens of states considering legislation to protect workers from such intrusions. A Senate bill advanced Wednesday would make it illegal for employers to demand online passwords or usernames or punish employees and applicants who refuse to provide such information.

Republican Sen. Rick Murphy, the bill's sponsor, noted that some businesses are concerned about any laws restricting them from disciplining employees or fully investigating job candidates. But Murphy said Arizona must find a balance.
