The term "working class" refers to a group of people who typically earn their living through manual labor or service jobs. This includes occupations like factory workers, construction workers, and nurses. Working-class individuals often do not have advanced degrees and may rely on hourly wages rather than salaries. Their work is essential for the economy, providing vital services and products. Historically, the working class has played a significant role in social movements, advocating for better wages, working conditions, and rights. Many labor unions represent their interests, helping to negotiate fair treatment and benefits. The struggles and achievements of the working class have shaped modern society.
