Threat of 999 strike action
Workers who take 999 calls have voted in favour of strike action in a dispute over pay and working conditions.
However, their employer Conduit has said it has drawn up a robust contingency plan that means there will be no disruption to services.
The staff recently claimed they were being treated like schoolchildren after they were informed they had to ask permission to go to the toilet.
The Communications Workers Union said 84pc of votes cast were in favour of industrial action. It called on Conduit to introduced a "living wage" of €11.50 an hour. The workers also want a "fair" on-call policy.
They claimed they had to report to management before and after their visits to the bathroom and were allowed just seven minutes for a toilet break.
BT Ireland, which is contracted to deliver the answering service, said operators were informed of minor changes to work practices but denied they had to report to management before and after a toilet break.
It said it has also implemented significant changes as a result of dialogue and only learned of the ballot result from the media.
