Treasurer Jim Chalmers said he is "disappointed" that Opposition leader Peter Dutton rejected his invitation to attend a national jobs summit. <br /><br />Mr Dutton received a letter formally inviting him to attend, but has labelled the event a "stunt with the unions".<br /><br />"We will support all sorts of good policy from the government, we've demonstrated that. But we're not going to support stunts," he told reporters in Brisbane on Wednesday.
