The cordial relationships JSS has with trade union organizations local as well as foreign help strengthening useful ties of brotherhood and solidarity in the world trade union movement. JSS has secured the affiliate membership of eight international trade union federations.
JSS is affiliated locally to National Trade Union Federation which consists of six unions as its members. They are
- Lanka Jathika Estate Workers' Union
- Jathika Adyapana Sevaka Sangamaya
- Public Service National Trade Union Federation
- Migrant Workers Front - MMF
- National Oraganization of self Employment - NOSE
- National Estate Services Union - NESU
In addition, JSS has established useful working relations with the following local organizations.
- Apparel Industry Labour Rights Movement
- National Association For Trade Union Research and Education
- Centre for Trade Union Unity
The foreign affiliations have provided opportunities, for the members of JSS to participate in overseas training courses, workshops and seminars.
The representation of JSS at high level international forums began in January, 1978 with the visit of Mr. K.D. Mendis, The General Secretary and Mr. Leslie Fernando, the Chief organizer to ILO Headquarters in Geneva. This was followed by a series of visits by JSS personnel for the participation in International Trade Union Conferences.
The JSS management is fully aware that it is essential for JSS personnel to clearly understand what their rights, duties and responsibilities are and to understand the policies, objectives and the programmers of the Jathika Sevaka Sangamaya. It is equally important for them to have some exposure to trade union practices in developed industrial nations.
Locally JSS had arranged several regional seminars, workshops and training courses, the aims of which were to provide the necessary knowledge and develop intellectual skills of planning, organizing, programming etc. In the conduct of training programmers, JSS was fortunate to benefit from the knowledge, expertise, resource personnel and facilities of the Labour Department, Sri Lanka Foundation Institute, Friedrich Ebert Sifting and the University of Colombo.
