PARAMEDICS in the ambulance service, who have just begun protest action in response to the Croke Park II proposals, say they cannot guarantee that patients will not be affected.
The National Ambulance Service Representative Association (NASRA) embarked on the first phase of the action, including withdrawal of the goodwill use of private mobiles while on duty.
They are also refusing non-rostered duty at public events and will only use the ambulance control sat-navigation system.
They are also refusing to use personal laptops to facilitate training and upskilling, said paramedic Michael Dixon.
"It's impossible to give a 100pc guarantee that people won't be affected," he said.
Normal rosters will apply for St Patrick's Day.
Meanwhile, the Irish Nurses and Midwives Organisation (INMO) has said that if a majority of union delegates on the ICTU public services committee vote to back the Croke Park revision proposals, the nurses' union would re-ballot members.
However, the outcome of this second ballot would remain undetermined.
Phil Ni Sheaghdha, of the INMO, told 'Industrial Relations News' that concessions made by the management side in the Croke Park talks were decided before her union walked out of the talks.
