He was featured anonymously.
Though it's possible that there is enough information (age, tenure, gender) in the article to identify him. A bit hard to say.
He'd also have a pretty clear cut case with the NLRB if he was fired or otherwise punished for talking to the press about labor conditions (which isn't to say that this doesn't happen sometimes anyways).
EDIT: Er, nevermind. I misread it as being told to Mark McCarter thinking he was the Vice journalist. But he's actually the factory employee and Lauren Gurley is the journalist. I'm an idiot. TY ALittleLight for pointing out my mistake.
