The broadcast union SAG-AFTRA said Wednesday that it had secured a majority of votes to represent staff members at Chicago Public Media. SAG-AFTRA said it would represent 49 editorial members of Chicago Public Media, the pubcaster that operates WBEZ and Vocalo. In September, 36 full-time editorial staff members and three additional employees signed a petition seeking union representation and presented it to CPM interim CEO Alison Scholly. “We have great leaders and a committed board and we believe organizing as staff members is an important step to achieving the goals we all share here: producing excellent journalism that serves the public and making this important local institution even stronger than it is today,” said Rob Wildeboer, criminal and legal affairs reporter for WBEZ, in a prepared statement. The National Labor Relations Board conducted the election, which took place Dec. 18.
