Employees at the Pittsburgh Post-Gazette have had concerns with John Robinson Block, the daily's publisher for over a few years now. Block had fired anti-Trump cartoonist and the journalist of an editorial regarding President Trump’s offensive language towards immigrants. The journalists’ union have become so fed up with Blocks behavior that they put up a “shame on the Blocks” poster in the newsroom, which sparked an outburst from Block. The union proceeded to file a federal labor complaint as some of the reporters are worried to return to work.
