The National Labor Relations Board has launched a webpage that describes the rights of employees to act together for their mutual aid and protection, even if they are not in a union.

The page tells the stories of more than a dozen recent cases involving protected concerted activity, which can be viewed by clicking points on a map. Among the cases: A construction crew fired after refusing to work in the rain near exposed electrical wires; a customer service representative who lost her job after discussing her wages with a coworker; an engineer at a vegetable packing plant fired after reporting safety concerns affecting other employees; a paramedic fired after posting work-related grievances on Facebook; and poultry workers fired after discussing their grievances with a newspaper reporter.
