A more thorough explanation:

A collective-labor agreement, also known as a collective-bargaining agreement, is a contract between an employer and a labor union that outlines the terms and conditions of employment. This agreement covers various aspects of employment, including wages, benefits, working conditions, and grievance procedures.

For example, a collective-labor agreement may specify that employees receive a certain hourly wage, have access to health insurance, and are entitled to a certain number of vacation days per year. It may also outline the process for resolving disputes between employees and management.

Collective-labor agreements are important because they provide a framework for fair and equitable treatment of employees. By negotiating with management as a group, employees can often secure better wages and benefits than they would be able to on their own.
