There is a possibility of more Luas strikes to be announced over the next few days.
It comes after talks have failed to resolve the pay dispute.
So far two 48 hour stoppages are to take place on the 11th,12th,18th and 19th of February.
Meanwhile strikes are also being considered by those who operate the 999 emergency call-answering service.
Workers are also looking for a pay increase, and believe that striking is the only way forward.
