Thomas Cook is seeking legal costs over the Dublin sit-in which shut its Grafton Street branch for five days during the Summer.
The company went to the High Court on October 22 seeking legal costs against those who defied a High Court order to stop the sit-in which was over the closure of its two shops and a Direct Holidays outlet in Dublin.
The company is seeking legal costs against the Transport Salaried Staff’s Association (TSSA) and a range of other third parties.
A spokesperson for Thomas Cook said: “Substantial costs were incurred by Thomas Cook due to the actions and behaviour of the TSSA Union and former staff.
“We fundamentally believe that it was the TSSA’s illegal actions in encouraging our former colleagues to protest, during the dispute last August, that were detrimental to the livelihoods of their families.
“As such we are seeking legal costs from the TSSA Union and other third parties involved.”
TSSA general secretary Gerry Doherty said the union was forced to strike as Thomas Cook was shutting the shops early meaning they could not take “legal industrial action.”
The judge adjourned his decision on costs claiming the case had some “unusual features”. The case continues.
