Tuesday roundup: Dingell to retire, PBS vs. NPR in March Madness, #SheDocs returns

• U.S. Rep. John Dingell, who helped sign the 1967 Public Broadcasting Act into law and remained a staunch supporter of pubcasting, is retiring after a record 58 years in Congress. “I find serving in the House to be obnoxious," the 88-year-old Michigan Democrat said at a Monday luncheon. "It’s become very hard because of the acrimony and bitterness, both in Congress and in the streets.”

• March Madness is approaching quickly, but this bracket competition has nothing to do with basketball. WHYY in Philadelphia is sponsoring PBS vs. NPR: Public Media Madness, which encourages pubmedia fans to vote for their favorite TV and radio personalities.

Chicago Public Media editorial staffers vote to join SAG-AFTRA union

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.
