Unite members at Mid Ulster District Council are planning to take part in a four-week strike unless they can reach an agreement over pay.
The discontinuous strike action is set to begin on July 25 and end on August 21.
The council has been served notice of the planned action by the union and talks are ongoing.
A union spokesperson said Derry City and Strabane District Council (DCSDC) had shown that a two- increment uplift in pay scales is possible and that pressure must be applied to Mid Ulster District Council to do the same.
A planned strike at DCSDC was suspended just a few days ago after negotiations between the council and Unite and NIPSA unions resulted in an improved pay offer.
In a statement released afterwards, a Unite spokesperson said: “During the meeting, the unions jointly acknowledged the improved proposals and ongoing positive engagement with council and advised that the decision to suspend the strike will allow time for the finalisation of the improved pay offer.
“Council welcomed the decision to suspend the strike and paid tribute to the positive engagement with the unions. Council advised it remained committed to continuing with further and final negotiations next week to arrive at a definite resolution to the pay dispute.”
A spokesperson for Mid Ulster District Council said today (Monday) that “discussions on the impact of planned industrial action are ongoing”.
