Ireland's government should be tougher on striking "overpaid" public workers if it wants to help the country get out of the economic recession, Ryanair CEO Michael O'Leary told CNBC Thursday.
Thousands of passengers were affected as the country's main airports in Dublin, Shannon and Cork were shut because of the strike which lasted four hours.
"The air traffic controllers are simply a bunch of overpaid, underworked public servants but they're typical for the problem in Ireland," O'Leary said.
He said traffic controllers' demands for a pay raise of 6 percent were unreasonable because they earn 160,000 euros a year ($224,000) and inflation is negative.
