Unions constitute one of the social organizations that have gained importance and social influence, particularly as the significance of work itself has increased. Trade unionism can be considered among the key indicators reflecting the levels of social, economic, and political conditions, as well as the degree of freedoms within society and the nature of social relationships, including the relationship between authority and civil society.
Unions play a vital role in representing and protecting the interests of workers in various fields of work. They strive to improve working conditions and secure better social and economic benefits for their members. The presence of unions can also reflect the degree of freedoms and the nature of social relationships, and shed light on the relationship between power and civil society.

Moreover, unions work towards enhancing workers' bargaining power, contributing to the preservation of ethical and social standards in the workplace. They aim to achieve a balance between workers' rights and the interests of employers, while promoting democratic participation and social justice within society.
