The Garda Representative Association has said it will ballot its members on any non-binding recommendations of the Labour Court in relation to the garda pay dispute.
The GRA said the industrial action scheduled for 4, 11, 18 and 25 November is set to go ahead unless the association hears of "substantial and significant progress towards real and tangible increases in pay".
The GRA says it remains fully engaged in the negotiation process.
A hearing at the Labour Court with the GRA, which represents rank-and-file gardaí, aimed at averting Friday’s planned strike is continuing.
Both the GRA and the Association of Garda Sergeants and Inspectors have rejected management proposals aimed at resolving the dispute.
The AGSI will attend the Labour Court tomorrow morning.
The 24-hour strike is due to go ahead on Friday, but it was hoped that if the Labour Court issues a recommendation, the two associations might agree to defer it pending a ballot of members.
Garda authorities are continuing to prepare contingency plans.
Senior gardaí are understood to be asking individual officers to confirm whether or not they are working on Friday following yesterday's directive from Commissioner Nóirín O'Sulllivan that they must attend for work.
Failure to obey the directive could result in disciplinary action.
The two garda associations held talks with Minister for Justice Frances Fitzgerald and Minister for Public Expenditure Paschal Donohoe last night.
GRA General Secretary Pat Ennis has written to members reiterating that the proposed withdrawal of labour is a matter for each individual garda to decide for themselves and stressed that the decision must be freely made, without inducement or coercion by any other member.
Authorities expect to have a tally on how many members might attend for work by tomorrow.
Meanwhile, the Civil Public and Services Union, which represents some civilian staff in An Garda Síochána has advised them that they should only perform their normal duties in the normal location and during their normal scheduled hours.
The union also informed their civilian members that the cancellation of all leave and rest days on Friday by the Garda Commissioner does not apply to them
AGSI President Antoinette Cunningham has said it is "regrettable" that they find themselves in this situation.
Speaking on RTÉ's Morning Ireland, Ms Cunningham said gardaí have always had a very good relationship with the public and "anything that would be done to damage that would be very regrettable."
However, she said she thinks there is a lot of public sympathy for gardaí in relation to this dispute.
"It's a four year dispute as far as the AGSI is concerned," she said.
"It has to end somewhere and prolonging this and not finding a resolution in the 48 hours would be wrong, because this is not something that should happen. We need to focus on getting an outcome to this dispute," she added.
Any liability for damage or docked pay as a result of this strike will be discussed with their legal team afterwards, she continued.
President of the Association of Garda Superintendents Noel Cunningham said contingency plans are being put in place, which will provide some level of service in the event the strike goes ahead.
He said superintendents will be at work on Friday, but said there is not the capacity to replace the thousands of gardaí who are planning to take action.
Mr Cunningham said he hoped there would be a positive outcome following attendance at the Labour Court.
