Talks aimed at resolving the electricians' dispute are due to resume at the Labour Relations Commission today after they were adjourned in the early hours of this morning.
The discussions appear to be making some progress, with employers apparently expressing a willingness to drop their demand for a 10% pay cut.
However, it remains unclear whether a deal can be reached.
The TEEU, which is demanding an 11% pay rise, is refusing to lift pickets across the country until a resolution is found.
More than 10,000 electricians are beginning a fourth day of strike action today at construction sites and manufacturing facilities across the country.
