Siptu's John Murphy has said that Luas drivers could vote for industrial action in a row over lunch, the Irish Times reports.
The dispute revolves around drivers having to start their day in Sandyford depot before being required to take lunch breaks in Broombridge, meaning they have to carry their lunch with them in a warm cab for hours.
Murphy said that he expected a Labour Court proposal aimed at resolving the dispute to be rejected by drivers. In a recommendation, the court said that it was 'reasonable for a Luas driver to be expected to take breaks at a depot other than the one where their shift started'.
Luas operator Transdev has provided more than 100 cooler bags in an attempt to resolve the row.
