Owner of the Grangemouth refinery Ineos, is expected to make a decision later today about the future of the Scottish plant.
Yesterday leaders of the Unite union met with government officials and Ineos management to bring an end to the dispute which has led to the closure of the petrochemical operation.
Following the meeting union leaders said they had accepted demands from the management in an effort to save 1,400 jobs.
"The unions have indicated to the company that in terms of their survival plan we have put forward our positive response to that," Len McCluskey, general secretary of the Unite union, told the BBC.
Ineos halted production last week at the 210,000 barrels-per-day refinery, which provides 70% of Scotland’s fuel, due to the dispute with Unite, Britain’s largest union.
Unite had initially encouraged members to reject the company’s plan to cut pension provisions and freeze pay, moves Ineos considers vital to a plan to stem losses at the plan
The company is expected to respond today.
