The question of employees' rights when it comes to social media is "the hottest issue going right now," said Dorraine Larison, a St. Cloud employment law attorney who frequently counsels businesses on developing social media policies.
Generally, employees don't enjoy broad First Amendment rights to say whatever they want without risk, Larison said. However, employees do have protections under the National Labor Relations Act, passed in 1935, which include the right to engage in "concerted activity" for collective bargaining or other mutual aid.
Although many workers don't realize it, the law applies to all employees, not just those who belong to a union, Larison said. Before the rise of social media, the law rarely was used in non-union workplaces, she said. Workers complained about their jobs, but not in such a visible way.
