A company that fired a worker after she posted negative remarks about her boss on Facebook has settled a complaint brought by the National Labor Relations Board by agreeing to revamp its rules to ensure they don't restrict workers' rights, the NLRB said.

A separate, private settlement was reached between the employer–ambulance service American Medical Response of Connecticut Inc.–and the employee, though terms of that agreement weren't immediately available. The worker, Dawnmarie Souza, was a member of the Teamsters union and the Teamsters represented her before the NLRB.

The case had become a test of how much latitude employees may have when posting comments about work matters from their home computers on social media sites such as Facebook.
