The Association of Garda Sergeants and Inspectors (AGSI) is preparing to stage a second 24 hour work to rule from 7am tomorrow.
The industrial action will involve 2,200 sergeants and inspectors refusing to log on to the Garda PULSE computer system, or to do certain other administrative duties.
This means that while crimes will still be recorded on the PULSE system by rank and file gardaí, sergeants and inspectors will not review and verify these inputs or detail what action is to be taken.
Unlike a week ago when a similar action took place, the AGSI has refused to grant an exemption for custody sergeants to use the computer system to process prisoners.
The sergeants and inspectors are due to join their 10,500 Garda Representative Association rank and file colleagues on 4 November in a complete withdrawal of labour over pay.
Talks between the GRA and the Department of Justice are due to resume tomorrow in a bid to avert next week's planned strike.
The Department of Justice has said it remains focused on engagement and on reaching a negotiated settlement with the Garda associations, and that discussions would continue to this end.
It added that it would not be commenting further at this stage.
