Kevin Healy and Karina Aedo-Aguilera host a 'Transport Week' May Day special, focusing on our Union History, and featuring Merri-bek Councillor and community activist Monica Harte. She discusses her previous work life as a bus driver and president of the Tramways Union (ATMOEA) during the Melbourne 1990 tram strike. Later, Jack Howard, social activist who has done history research for the Rail, Tram & Bus Union (RTBU) Victoria, joins the conversation with an abridged history of our transport unions from the early 1900s to present.
