Informed that management plans major changes, including some layoffs, journalists at the Cleveland Plain Dealer are taking matters into their own hands with a proactive campaign that includes an ad in their own paper, bus, billboard, radio and TV ads, a Twitter feed and a Facebook ad, and mass emailings to influential folks. The gist of the message is on one of the billboards: "Save The Plain Dealer. Don't let Cleveland's daily paper fade away." Management hasn't said whether the changes will include a reduced publication schedule, but the journalists don't seem to be taking any chances.
