Tesco has confirmed it'll be checking out of Ballymun Shopping Centre at the end of next month.
All 52 staff at the supermarket have been told they'll be offered work in other Tesco stores nearby.
Local TDs are calling on NAMA which has control of the shopping centre to lay out its plans for the future.
Labour's John Lyons says there needs to be a clear strategy of what sort of facilities are going to be in place for the people of Ballymun.
