No public sympathy if you strike, Varadkar warns Aer Lingus staff
He has intervened in the row between airport employees and management, calling on both sides to help avoid damaging industrial action.
The minister urged an early pensions deal even though Siptu has claimed that employers have failed to engage in meaningful discussions on the deficit in the Irish Airlines Superannuation Scheme (IASS).
As the workers engage in a strike ballot, the minister said there would be no public sympathy for a dispute which risks disrupting St Patrick's Day holiday travel and key rugby matches.
"The solution is a simple one - the company will have to put in more money and the pensioners and the members will have to take less benefits.
"So let's avoid a strike," Mr Varadkar said.
