Electrical engineers have struck over a cost of their work and a pay increase.
The Department of Arts and Humanities and Science said on Friday that it will not pay more than €300 a week for each of its 12 full-time and eight part-time staff, who have worked on the site since the end of March.
The department said it will also continue to pay overtime for all the staff who work on the department’s site, which is owned by a subsidiary of a company called MCC.
The department said that in the next 12 months it will pay at least €1.5m more than it was paying in March.
The union representing the workers said that this was unacceptable.
“We are not paying more because we don’t think we’re going to make the same as we did in March,” said Frances O’Brien, a member of the Irish Electrical and Electronic Workers’ Union.
However, the Department of Art said that it would continue to increase the pay it offers to its staff.
MCC, which also operates the site, said that the strike would continue until it gets the department to pay it the amount it requested.
Meanwhile, there is a proposal to increase public transport fares in the city by €2.50 a day.
It comes after a €1,000 fine imposed on a number of transport companies for charging customers for travel to and from the site.
