The 11th work stoppage is scheduled to take place this coming Friday, May 13th
Luas drivers are expected to serve notice today of up to eight extra strike days for next month.
Dublin tram services were suspended for the 10th time last week as drivers took to the picket line in the long-running dispute over pay.
Some 90,000 passengers were affected during the strike last Wednesday.
Luas operator Transdev stands to lose €100,000 every day the drivers strike, and management at the company insist that the 23% pay claim sought by the workers is 'unaffordable'.
Luas drivers, who are represented by SIPTU, have vowed to push on with their pay claim - despite Transdev implementing a 10% pay cut as the drivers continue to strike.
Four more days of industrial action are currently planned for May 13th, 20th, 26th and 27th.
