By what means can the consumers express their solidarity?
Consumers can express their solidarity through active involvement and voluntary effort, as the consumer movement requires the participation of one and all to be effective.
One significant means is the formation of consumer forums or consumer protection councils. These organisations guide consumers on filing cases in Consumer Disputes Redressal Commissions and represent them. Similarly, Residents’ Welfare Associations express solidarity by taking up cases against unfair trade practices on behalf of their members.
Additionally, consumers can engage in writing articles and holding exhibitions to create awareness. They may also form consumer groups to investigate malpractices in ration shops and passenger transport, strengthening the movement as a social force.
