Thousands of bus passengers will be left without transport over one of the busiest bank holiday weekends this year as drivers remain committed to a "rolling strike".
Trade unions representing embattled Dublin Bus workers warned their strike from midnight on Saturday will continue until the company reverses controversial pay cut plans.
As Dublin Bus insisted it has no choice but to introduce 11.7 million euro of cost-saving measures, a spokesman for the National Bus and Rail Union (NBRU) said "enough is enough".
He added: "Unless the company reverses its position in relation to the implementation of these unfair measures, we will go ahead with this strike.
"It is public who are going to lose out, which is unfortunate. But we will continue this rolling strike until Dublin Bus changes its position."
Thousands travelling from the Oxygen music festival in Co Kildare, which will take place from Friday to Monday, could be left without transport.
Meanwhile, organisers of The Gathering Ireland have predicted the busiest weekend of the year for family and community events. Around 87 separate gatherings are planned across the country with a huge portion of those happening in the capital.
The NBRU and Siptu unions served strike notice on Dublin Bus earlier this week.
The struggling bus company is to implement a cost recovery plan from Sunday, which was drafted up following a series of recommendations from the Labour Court.
In a statement, Dublin Bus insisted the plan is "critical" to achieve the 11.7 million euro necessary to bring it back to financial stability. Around two-thirds of that portion - 7.7 million euro - will come from direct payroll costs, and the remaining 4 million euro from efficiency and productivity savings.
