Journalists are flawed humans like everyone else and expecting them to produce complete and objective reporting is not only unfair it is literally impossible.
So no, I do not believe there is such a thing as objective reporting generated by a single human or a single organization. The only true, unbiased journalism would be some sort of technology that could let everyone view the full entirety of any event from any perspective without a human brain and sensory system in between. That's not practical.
Practically speaking, it is up to the reader to consume as many varying sources as possible and then come to their own conclusion. But who has time for that?
When you want to validate a piece of information in your view of the world (to use your example, "how common is labor action?"), the most important question to ask (and often the question with the most obscure answer) is "what is the base rate?".
Editorials are not journalism, but when the journalism disagrees with people who are accustomed to the nature of the editorials they enjoy, they then see bias on the part of the journalists instead of the commentators.
