O'Leary's rant at FG fundraiser lashes out at Gardai
He also criticised the early retirement policy in An Garda Siochana, which allows gardai retire when they are aged 50.
"Why aren't you working till you're 65, and we'll also promote you to be deputy inspector or something in the last year of your employment so you get higher bloody pensions for the rest of your life, which you don't contribute or pay for, that we do," he said.
He also questioned why Dublin Bus and Bus Eireann union chiefs sought meetings with Transport Minister Shane Ross over pay when they should be seeking to talk with company managers.
Mr O'Leary insisted the Government should open up bus routes to private operators if drivers go on strike again.
"If they don't want to work, let somebody else do their jobs, let's allow more competition, let's continue to roll out more competition, let's make Ireland even more competitive," he added.
"I find it mystifying why we don't allow Swords Express and all the other private bus operators on a day when the State-funded workers go on strike.
"Off you go boys... get down the bus lanes, operate as many private second bus services as you like," he added.
Yesterday a spokesman for Ryanair said: "Michael spoke at a business breakfast for Fine Gael during the week and will be speaking at one for Fianna Fail in November."
