picketing

Definition from Nolo’s Plain-English Law Dictionary

Protesting, typically by standing outside of a business or workplace to publicize a dispute or incident occuring there. Sometimes, picketers want to persuade others not to enter the place they are picketing (as might be the case with workers on strike or antiabortion protesters outside of an abortion clinic). Picketing may also happen online, as when IBM's campus on the Second Life website was picketed by avatars of IBM employees.
