All workers were placed on protective notice by Transdev yesterday in a protracted dispute over pay.
The firm says it's costing 100-thousand Euro every day the tram isn't running – there have been 8 strike days so far.
It's also warning that pay could be docked to recoup losses.
Managing Director of Transdev Gerry Madden says the row is putting its contract to run the Luas service in jeopardy – but letting workers go with only a day's notice is still a last resort.
