One of the unions representing Dublin Bus drivers has again warned of an all-out strike.
Workers have already undertaken six days of industrial action, with further stoppages planned for Tuesday and Wednesday as well as 11 more days in October.
This includes next Saturday, October 1, when Mayo will once again face Dublin in the All-Ireland Football final replay, which is set to impact more than 80,000 fans heading to Croke Park.
Despite both sides saying they are willing to negotiate, the dispute shows no sign of ending.
Dermot O'Leary of the NBRU said: "At this stage people are very, very frustrated after six days and heading into another three days, people are very frustrated.
"But the one thing bus drivers will tell you is that they want this dispute resolved immediately and they didn't want to go on strike in the first place.
"So the resolve that is there to settle the dispute is similar to the resolve that is there to see it out to the bitter end."
