NLRB Concerted Activity Map
The Board says, “If employees are fired, suspended, or otherwise penalized for taking part in protected group activity, the National Labor Relations Board will fight to restore what was unlawfully taken away.

Recent cases involving a range of industries and employees are highlighted on the map below; please hover over a pin for a summary or click and the full story will appear below.”
