What concept is used to describe a collective movement towards social change based on shared class interests?

The concept that describes a collective movement towards social change based on shared class interests is class consciousness. This term refers to an awareness among members of a particular social class about their shared interests, conditions, and the social structures that affect them. When individuals develop class consciousness, they recognize their common experiences and challenges, which can motivate them to unite and advocate for social change that benefits their class.

In sociological terms, class consciousness is crucial for understanding how social movements form and how marginalized or oppressed groups mobilize for change. It emphasizes the role of social structure in shaping individuals' identities and actions, aligning them with others who have similar socioeconomic standings.

Other concepts like social mobility refer to the ability of individuals to change their social status, which does not inherently involve collective action or shared interests for social change. Collective bargaining is a process conducted between employers and a group of employees aimed at negotiating the terms of employment. Social identity pertains to how individuals define themselves in relation to groups they are part of, which may not explicitly focus on class-based interests or collective movements.
