 Rumours about the long-term viability of TrentonWorks began to circulate in late 2006 and early 2007 as the union began discussing the possibility of strike action to drain the union local's strike pay accounts, in advance of a possible long-term layoff or permanent closure.The union instead offered generous concessions which were followed on April 3, 2007 by a generous offer of financial assistance from the provincial and federal governments, which would subsidize the cost per railcar at Greenbrier's TrentonWorks plant.All offers of assistance from the union and governments were rejected by Greenbrier on April 4, 2007 when the company announced that its TrentonWorks plant would close permanently later in the year once current orders are completed.
