Consumer boycotts occur when individuals or groups refuse to purchase products or services from a company to express disapproval of its practices or policies. This collective action aims to pressure the company to change its behavior, often related to issues like labor rights, environmental concerns, or ethical practices. These boycotts can be organized through social media, community groups, or advocacy organizations. Successful consumer boycotts can lead to significant financial losses for the targeted company, prompting them to reconsider their actions. Notable examples include the Montgomery Bus Boycott and the Nestlé boycott over infant formula marketing practices.
