As I understand it Harley is heavily unionized...FWIW
I'm trying to understand your angle here. Do you think some of this is motivated because he also owns a Honda dealership?
They should be focusing on their bottom line. Does this guy sell enough of our product, or can we get someone else to serve the area better?
That's the primary question Harley should be worrying about.
Also, do they have any sort of loyalty to the people who have been doing business with them for all these years? They throw him under the bus over a not particularly egregious rant?
