Final answer:
A written rebuttal by an employee regarding a collective bargaining agreement violation or workplace issue is known as a grievance. It is a formal complaint as part of a grievance procedure within union workplaces to address and resolve such issues.
Step-by-step explanation:
An employee's written rebuttal about a perceived violation of a collective bargaining agreement or workplace dissatisfaction is known as a D. Grievance. In the context of labor relations, a grievance is a formal complaint that is raised by an employee or a group of employees towards an employer. The purpose of a grievance is to enforce the terms of the collective bargaining agreement, and it is a part of the grievance procedure, which is a systematic, step-by-step process designed to settle disputes between the union and the employer. Filing a grievance is a recognized right in most union workplaces, and the specifics of how grievances are addressed are typically included in the collective bargaining agreement itself. This formal process ensures that employees have a means of communicating their concerns and seeking resolutions to issues related to work conditions, pay, benefits, or other work-related matters.
