Members of the union Unite are due to vote on whether to accept proposals aimed at stopping a strike by fuel tanker drivers. They were drawn up during six days of negotiations at the conciliation service Acas.
The talks ended last Friday but neither the employers nor the Unite union have released any details of the discussions before today's meeting.
Proposals aimed at resolving the fuel tanker drivers dispute were drawn up tonight, raising hopes that strikes can be averted.
The deadline extension suggests talks are going well, but the deadline of next Friday to reach a deal is still very tight.
Private talks have begun to avert a fuel tanker strike, as petrol prices continue to soar at the pumps.
