SIPTU has accepted an invitation to attend a Labour Court hearing to discuss the dispute involving 10,000 health service workers.
This includes workers at Naas General Hospital.
A three day strike due to take place last month was deferred to allow for talks.
The dispute involving health care workers such as porters and chefs centres on a job evaluation scheme and pay grades.
The union is due to attend the Labour Court on Monday July 22nd.
SIPTU says further strike action remains deferred pending the outcome of the talks.
