Both sides in the Aer Lingus dispute will meet at the Labour Court on Monday to try and resolve their row.
It comes after Ialpa pilots walked off the job on Saturday in an eight-hour strike.
Work to rule industrial action has been taking place since Wednesday in their bid to get a pay hike.
Taoiseach Simon Harris said the Government has already intervened in Aer Lingus pilot pay dispute but encouraged both sides to "dig deep".
Mr Harris said the Government has done what it can but that both sides need to sort this out quickly.
"The State already has made an intervention through the Labour Court, so the Labour Court has already met both parties separately in the last couple of days.
"But on that occasion, they said 'hang on a second, you guys are too far apart, we'll be back to you in a few days', and the private conversations, I'm sure took place. Now on Monday, the Labour Court will again meet, so that is Government, through its industrial relations mechanism endeavouring to make progress."
