Gherao
Gherao, meaning "encirclement," is a word originally from Hindi/Bengali/Marathi. It denotes a tactic used by labour activists and union leaders in India. Usually, a group of people would surround a politician or a government building until their demands are met, or answers given. This principle was introduced as a formal means of protest in the labour sector by Subodh Banarjee, the PWD and Labor Minister in the 1967 and 1969 United Front Governments of West Bengal, respectively.
