The company that operates Ireland's 999 call centres says it will not recognise the Communication Workers' Union.
Conduit Global has again refuted claims from the union that staff have been subject to a toilet break policy.
It says the average pay is already above the living wage and that a number of measures have been put in place following negotiations with employees.
The CWU has announced industrial action for next week, but Conduit Global says it believes the employees are their own best representatives, and this is why it will not recognise the CWU.
BT which runs the facilities says despite media notifications the firm has yet to be informed of any action by staff.
