There could be further strike action at Dublin Bus in the coming weeks ahead in a dispute over pay and pensions.
It is understood union members will hold a ballot for industrial action late next week, which could see the possibility of an all out strike.
The possible strike action comes after management at Dublin Bus failed to honour the terms of the Workplace Relations Commission document agreed upon by workers a number of weeks ago.
Staff say they feel strike action may be necessary as they are angered about the failure to restore the normal link between pay and pensions.
