Businesses in Dublin say the Irish Rail strikes will cost the city up to 30 million euro per day.
DublinTown says more than 10 per cent of the people who travel into the capital every day use train - and it's critical for the city's economy.
The group is urging both sides to return to the table - ahead of tomorrow and Monday's work stoppages.
DublinTown CEO Richard Guiney says the disruption will have a huge impact on the city.
