That jumped out at me too. My reading was the implication that if there was a union, you would lose that. It seems like a common anti-union talking point, from what I've seen at Walmart and Whole Foods.
In my experience being in a union (against my preferences) it’s not implied, but a fact. Unions have sued their own members for speaking with managers about grievances.
Or is it "Hi Boss we come from the same village / clan /race how about you put me on that sweet work detail/shift".
I have (in the UK) personally overheard a guy working at a well known company say this - Also Fords at Dagenham had a scandal where white workers monopolised the better jobs.
