Trade unions have so far collected 320,000 of the 450,000 signatures of voters required for calling a referendum on government-proposed amendments to labour legislation.
Union leader Kresimir Sever on Wednesday called on union members and other citizens not to grow weary of the signature-collecting campaign, which was launched by trade union federations on June 9.
They have until June 23 to collect around 450,000 signatures, or 10 percent of the electorate, in order to initiate the referendum procedure.
