This article was researched within the FP7 Program Support Marie Curie (IRSES) “Possibilities and limits, challenges and obstacles of transferring CEE EU pre-accession best practices and experience to Moldova’s and Georgia's pre-accession process”. The history of trade union movement in Moldova has over 100 years. The last two decades can be considered as the contemporary stage of development of trade unions.The characteristic of this period is the inconsistency and complexity of processes and tendencies, such as a reduction in the number and fragmentation of structures, democratization of the trade union movement, dividing and unifying their unions etc. It should be noted that trade union activities in Moldova have both traditional approach to the trade union movement, but also new activities associated with the need to address employment issues characteristic to market economies in the globalized world. On the other hand, the development of new practices and methods reflects the expansion of democracy in the country and influence on the international trade union movement. Trade unions activities aimed at solving problems that were not known (right to work and employment), search strategies appropriate to the new conditions of market relations (employer dialogue at all levels). Improved efficiency tactics used by unions contributes to potential democracy use, to promotion of dialogue within unions, to development of union movement internationally (protection and legalization of labor informal gender politics and youth), and finally, to involvement and use of science, informational resource, media in the daily practice of the unions.
