A more thorough explanation: In legal terms, “picket” refers to the act of demonstrating or protesting by standing or marching near a place of work or other location, typically carrying signs or banners to communicate a message. Picketing is often used as a form of peaceful protest to raise awareness of a particular issue or to put pressure on an employer or organization to address certain concerns.
