News anchors quit live on air - video
Cindy Michaels and Tony Consiglio of ABC's WVII affiliate in Bangor, Maine, announced their joint resignation on the show, and spoke of a dispute with management over journalistic methods.
Michaels told viewers: "And finally tonight, this will be Tony and my final show together right here on ABC 7. The last six years have been an interesting and enjoyable time for us as we have been the longest-running news team in Bangor."
Consiglio added: "On behalf of Cindy and me, we have loved every moment bringing the news to you. Some recent developments have come to our attention, though, and departing together is the best alternative."
The pair explained their decision to the Bangor Daily News later, with Michaels saying: "There was a constant disrespecting and belittling of staff.
"We both felt there was a lack of knowledge from ownership and upper management in running a newsroom to the extent that I was not allowed to structure and direct them professionally. I couldn't do everything I wanted to as a news director. There was a regular undoing of decisions."
She added: "It's a culmination of ongoing occurrences that took place the last several years and basically involved upper-management practices that we both strongly disagreed with.
"It's a little complicated, but we were expected to do somewhat unbalanced news, politically, in general."
However, the station dismissed the claims made by Michaels, with vice president Mike Palmer telling The AP: "Upper management is not involved in the daily production of the news, period.
"We've made great changes over the last few months and are not slowing down. Over the last 15 to 18 months, we've been a raging locomotive of change."
He added that the pair "were on their way out, anyway", and that "sometimes people leave their jobs before they're asked to leave".
Cindy Michaels, 46, said she will stay in Bangor to start work on a novel, while Tony Consiglio, 28, said he will continue his career "in another capacity".
