He said: "I don't think that is the way we do pay in this country.
"The way we do pay in this country in the public sector, rightly, is we have independent pay review bodies."
But he added: "Everybody knows public-sector pay is going to be much tighter than it was in the past. Here we are in 2009 - we don't know exactly what inflation will be in the future so I don't think it's the right time to make this decision."
