Answer:
Primary boycott
Explanation:
Primary boycott is a form of organized protest that is being done by cutting the flow of consumers toward a certain company. This is aimed to eliminate company's income until they're willing to have a conversation with the protesters.
This can be done by forcing the members of the group to stop purchasing a certain product, influence the public to purchase the company's product, or in a certain capacity physically prevented the customers from entering the business establishment (such as chaining themselves up in the company's front door)
