Dublin Bus workers say they still plan to strike on the day of the All-Ireland replay.
The NBRU insists calls to consider the suspension of a 24-hour stoppage during the All-Ireland final replay on October 1st are "premature".
At the moment, a strike is scheduled to go ahead when Dublin meet Mayo again.
Dublin Bus has received notification from SIPTU of plans for further industrial action on September 27th and 28th - as well as October 5th, 7th, 10th, 12th, 14th, 18th, 19th, 24th, 26th, 29th.
This is in pursuit of a 15% flat pay increase over the next three years.
The company says industrial action is "unnecessary and unjustified and will continue to cause significant disruption to our customers and trade in Dublin city".
To date, it says, work stoppages have cost it in excess of €4m.
But Dermot O'Leary of the NBRU told Newstalk Breakfast that there are some things that are more important than sport.
"There are 400,000 people that want this dispute resolved for them to attend their work, college and hospital on a regular, daily basis.
"The football match, as important as it is - and we all love our sport in this country - that's secondary when it comes to resolving this dispute."
He said all the unions are prepared to return to the negotiating table.
