Which groups are recognized in the mutual interests by the CIR?

The correct answer is based on the recognition that the mutual interests in the context of labor relations often involve the collaboration and communication between the public sector, employers, and employees. Each of these groups plays a crucial role in the functioning of the workplace and the economy at large.

The public represents the interests of society and can influence labor policies and practices through regulations and legislation. Employers seek to operate their businesses effectively while ensuring compliance with labor laws, and employees aim to secure fair wages, safe working conditions, and job security. The alignment of interests among these three parties is essential for promoting positive labor relations and achieving economic stability.

The other groups listed in the other options involve components that do not completely encapsulate the mutual interests in labor relations or may emphasize narrower or less direct relationships. For instance, while contractors can play significant roles in specific projects, their interests don't encompass the broader dynamics of labor relations as seen among public, employers, and employees.
