Fórsa, the trade union representing striking school secretaries and caretakers, has said a growing number of Government TDs, Senators and MEPs have pledged their support for the school staff.
The workers marked their fourth day of indefinite strike action today by travelling to Leinster House and TD constituency offices around the country.
The union said that while many politicians have committed to writing to their party leaders seeking intervention in the dispute, the expressions of support have not yet materialised into talks that could bring the strike action to an end.
Around 2,600 school secretaries and caretakers began indefinite strike action last Thursday demanding access to public sector pensions and other entitlements.
"We've had strong expressions of support from 40 Government representatives so far, including 29 TDs, one minister, a minister of state, four senators and three MEPs," said Fórsa's Head of Education Andy Pike.
"The level of expressed support comes as no surprise and reflects the huge level of support already expressed by Opposition TDs and senators, as well as local authority representatives of all parties and none."
"Nevertheless, this strike action continues because, despite the considerable noise made by school secretaries and caretakers at Government buildings today, the silence from within those buildings remains absolute," Mr Pike said.
Exploratory talks at the Workplace Relations Commission last week failed to avert the strike action.
Minister for Education Helen McEntee has previously said that her department is willing and ready to meet with Fórsa at the WRC to resolve the dispute.
The Department of Education has instructed schools to open as normal but unions have told their members to support the striking workers by refusing to carry out the duties of secretaries and caretakers.
