We hear from Tripoli as the Libyan capital comes under fire from General Haftar, the man praised by Donald Trump as a fighter against terrorism. Haiti's foreign minister Bocchit Edmond tells us how his country is trying to reinvigorate its coffee industry, decimated by an earthquake nine years ago. We examine aerotoxicity and allegations that aircrew and passengers can suffer ill-effects from the air they breathe. Plus, how far can employees go to stop their boss from doing what he shouldn't? We get advice from workplace guru and author Mary Abbajay. Roger Hearing is joined by political journalist Erin Delmore in New York and Peter Ryan, ABC Australia's senior business correspondent in Sydney.
