With no other way to find solution in a dispute over new labour contracts and wages Polish miners went on 24-hour strike on 19 October 2012.
The strike started on 6:00 a.m. at Jastrzebska Spolka Weglowa SA (JSW SA). The strike was organized by the local union organization in JSW SA, a member of the Trade Unions Alliance "KADRA", affiliated to the IndustriALL Global Union.
The strike is the result of a disagreement with the management board of JSW SA regarding the introduction of new labour contracts for newly hired employees and wages. The management intends to impose contracts violating the national labour law as well as the previous agreement with the trade unions, particularly the agreement of May 2012 concerning the privatization of JSW SA.
The union demands withdrawal of unfavourable contracts for new employees and an increase of salaries by 3.8 per cent. The company declared 50 per cent of workers participated in the strike and announced Z17million (4.1 million euros) losses in revenues as the direct result of the strike. The union dismisses the data as unreliable. During the press-conference about the results of the strike on 25 October the union declared its readiness to continue the struggle.
