"The coalminers are not sure that they'll get payment in January and in February. The local organization of the independent workers of Ukraine had a meeting yesterday. Another trade union is also about to act. A decision was taken to hold meetings at other coalmines in Lviv region, which should decide whether they are going to join the strike or not," Volynets wrote on Facebook on Monday.

He wrote the miners would block the customs checkpoints with Poland on January 12 to attract the public's attention.
