I don't want to assume, but I'm curious if you read the documents I linked. Your reply doesn't seem to address contradictory data I've provided. To address your second point; If Walmart was consistently discussed negatively in conversation, on social media, in the news, etc. I'd say that they were portrayed negatively, yes. That said, my second link is explicitly about media portrayals, indicating that corporate media intentionally over-represents negative elements of unions, so even excluding the semantics regarding whether or not 'word of mouth' portrayals count as portrayals, the point stands.
