Detroit has long been known as a labor town.
The annual Labor Day parades held this weekend drew thousands of people across Michigan.
But experts say those parades have seen attendance dwindle as organized labor itself has lost both membership and clout in recent decades.
Yet the head of one influential union, Teamsters General President James P. Hoffa, says organized labor groups now have the chance to draw closer together than ever before.
The reason, Hoffa tells WDET’s Quinn Klinefelter, is that labor leaders feel all unions are facing an unprecedented level of attacks.
