This chapter explores the role of law in addressing workplace bullying by summarizing existing labor and employment laws that potentially apply to claims of workplace bullying, and by examining various legal proposals aimed at deterring bullying behavior and providing legal redress for aggrieved individuals. In addition to exploring existing and proposed federal and state laws in the United States, selected comparative experiences of other countries are reviewed with the aim of drawing lessons for the role of law in the United States. This chapter will also briefly review the potential role for self-governance initiatives, such as internal company or union-initiated policies addressing workplace bullying.
