Minister for Transport Leo Varadkar has called on both sides in the Aer Lingus dispute to go for arbitration at the Labour Relations Commission.
He said the Government is very concerned at the third recent threat of strike action at the airline.
The action by cabin crew represented by IMPACT is planned for Friday 30 May, leading into the June bank holiday weekend.
Aer Lingus yesterday claimed that cabin crew were seeking an additional 32 paid days off a year.
IMPACT served notice of the industrial action in a row over rosters, which it says place excessive demands on staff.
It says it is seeking the same roster arrangements that have been granted to pilots.
Aer Lingus says that if the strike goes ahead, it will disrupt 204 flights and the travel plans of 28,000 customers.
The airline says it would normally expect to carry in excess of 40,000 passengers on the Friday before the bank holiday, but it has already had to stop taking additional bookings because of the threatened industrial action.
