The social dialogue is a form of communication, information and collective bargaining between employees or their representatives, on the one hand, employers or their representatives, on the other hand, with the participation of the state as a mediator and arbitrator, to solve collective problems, to harmonize the patrons' interests with those of employees. The actors in the social dialogue are the ones that materialize this phenomenon, they are employees (usually organized in trade unions), employers (largely associated with employers' organizations) and the state (usually represented by the government). Trade unions are an important factor of social equilibrium, one of the essential institutions of civil society and democracy. They play a special role in the social dialogue by protecting the rights of its members arising from labor law and collective labor agreements, but also through its impact on the country's economic and social development.
