Trade union Unite said the arrest of some 30 Thomas Cook workers at the company's Grafton St premises this morning was "a dark stain on the history of industrial relations in Ireland".
The workers, who had been engaged in a protest sit-in at the premises, were removed by gardaí following a ruling by the High Court ordering the workers to leave the premises by 7pm yesterday.
“These are ordinary working people standing up for their rights,” said regional secretary of Unite Jimmy Kelly.
“They have a right to be treated with respect and for their employer to hold to a standard of engagement that, in this case, has merely been cast aside.”
Thomas Cook is to close its two stores in Dublin, with the loss of more than 70 jobs. Workers at the Grafton St premises are arguing for a better redundancy deal from the travel agency.
