Since its founding, the Pancyprian Federation of Labor (ΠΕΟ) has led the charge in the socio-economic struggles of the Cypriot people, as in the example of the strikes of the 1st of March of 1944 demanding the price indexation of wages. The strike took place at the Public Works from the 1st to the 23rd of March with 1,500 workers participating.
Ιn 1946, at ΠEO’s initiative, the struggle for Social Security also began. In 1948, the first Trade Union Social Security Fund was established, as well as the first Union infirmary. In 1956, the Social Security law was drafted, and was put into effect in the first of July 1957.
