The referendum question, however, will not be about amendments to labour legislation, but will read: "Do you agree that a referendum must be called if so requested by 200,000 registered voters and that the time for the collection of the required number of voters' signatures should be 30 days?"
The referendum is to be held in mid-2011, after Croatia completes accession negotiations with the European Union, Prime Minister Jadranka Kosor said.
As regards changes to the Labour Act, the government and the trade union federations signed an agreement settling all outstanding issues.
