The Chicago News Guild will picket the Chicago Sun-Times building Thursday morning, the Guild said in a press release.

The Sun-Times laid off its photo staff last week and announced plans to train reporters in iPhone photography.

The event "will make a statement to the company that people care about quality journalism," the release reads.

Guild members clad in black ("for mourning," they explained) attempted Monday to deliver a petition to Timothy Knight, the CEO of Wrapports, LLC, which owns the Sun-Times.
