The IMPACT trade union has warned that talks at the Labour Relations Commission today represent the last chance to avert strike action in South Dublin County Council this Thursday.
The dispute centres on a decision by the council to withdraw acting-up and project allowances paid to staff for performing additional duties.
The strike on 24 June saw 600 union members involved in the industrial action.
It led to the closure of a wide-range of council services.
Limited industrial action, which has been under way for the past five weeks, is continuing.
