Leave it to the Estonians and Finns to answer that question many years after it was posed...
The top employee organisations in Estonia and Finland have agreed to harmonise the supervision of workers' rights between the two countries.
The chairmen of the Central Organisation of Finnish Trade Unions (SAK), the Finnish Confederation of Salaried Employees (STTK), the Confederation of Unions for Academic Professionals in Finland (Akava), the Confederation of Estonian Trade Unions (EAKL) and the Estonian Employees´ Unions´ Confederation (Talo) signed a deal in Tallinn on Thursday.
A transition period limiting the access of Estonians to the Finnish labour market expired on May Day.
The organisations said the unions should do everything in their power to ensure the smooth flow of information across the Gulf of Finland.
This is also further proof that the "Talsinki" meme - that Tallinn is just a suburb of Helsinki, that Estonian and Finnish are actually two dialects of one huge Finnic language group, that the future will be just one big, warm sauna, goes beyond the existence of the 'Talsinki' Rugby Team - which combines Helsinki's Rubgy Club with the Tallinn Tigers.
Sure there are the little differences. While 'hyvää' in Finland is 'good', 'hüva' in Estonia is just 'ok.'
