Niksic (MINA-BUSINESS) – Workers at the Trebjesa brewery from Niksic launched on Monday a general strike over the management#s refusal to sign a collective agreement, chairman of the trade union Bozidar Petrovic said. "We want clean bills, and that does not suit the manager," Petrovic told Mina-business. The workers said they did not expect the management to agree to negotiate in the first week of the strike as there had been sufficient quantities of beer on stock. This is the third strike at Trebjesa. The first one lasted 11 days and the second one 19 days, but workers said they would be more persistent this time.
