Budget Travel has confirmed it is to close 14 shops with the loss of 95 jobs across Ireland from next week.
The shops to close are in Athlone, Clonmel, Cork, Dublin, Dundalk, Ennis, Limerick, Mulingar, Tralee, Wexford.
The company, which operates 39 shops throughout Ireland, said another four shops are under "serious threat".
Workers being made redundant will receive the minimum pay of two weeks for every year of service.
Gerry Doherty of the Transport Salaried Staffs' Association (TSSA) said the company is treating its staff like "second class citizens".
"Budget Travel is part of a hugely profitable Scandavian group-Primera Travel-which can easily afford to treat its Irish staff decently. Other travel companies, like Falcon, have paid their staff four weeks per year when they have hit trouble," he said.
