According to the Law on Syndicates (No.1129-XIV/2000), Trade Unions are defined as social organizations formed on benevolent principles of entities united by common interests, including the ones that deal with their activity and which are constituted in the aim of defending the professional, economic, labour and social collective and individual rights and interests. The present article reveals the fact that according to the legislation in force different categories of people can form a syndicate. Employees, public functionaries, free lance professionals (lawyers, notaries) etc can be among these. Neither the Code on Labour of January 28, 2003, nor the Law on Syndicates restricts the citizens’ rights to associate in trade unions.
