But they did investigate. They interviewed sources who confirmed that unionizing was planned before people were fired, which is the title. And they read the lawsuit and talked to the lawyers, who obviously said the same thing.
You probably don't see the bias in the article because you support unionization. If the article was instead titled "Sexual harassment complaints double after NPM staff unionize," you'd probably be complaining about bias the same as I am.
Erm, yeah, I'm not sure where to begin with this other than a "people in glass houses" style comment.
