According to the paper, representatives of the Kremikovtzi trade unions had had negotiations on Saturday with Miroslav Borisov, the CEO of the ProMet steel factory, which is located in Bulgaria`s city of Burgas, and is owned by Rinat Akhmetov.

Another meeting between the trade unionists and representatives of the Ukrainian tycoon is scheduled for Monday to hammer out the details for the actual negotiations on Wednesday, which might be attended by Akhmetov himself, according to the Standart Daily.
