The National Labor Relations Board (NLRB) filed a complaint against an emergency medical response company that fired an employee for violating a policy of barring employees from commenting on the company on Facebook or other social media. An employee was upset when the employer refused to allow her union rep to help her prepare a respond to a customer complaint. The employee then mocked the supervisor on Facebook. The NLRB's position is that the policy violates the prohibition against employers discussing working conditions. The case is pending. Employers may want to review their policies on social networking to determine whether it is susceptible to the charge that it chills employees' right to discuss working conditions and unionization.
