Wouldn’t that be considered cyberstalking/harrasment by searching for, obtaining, and using any business employee’s personal contact info for matters related to their business in most places in the world?

Yes, I understand that in places like the USA that info is technically public info usually, but I feel like contacting someone’s private contact for matters related to their business is crossing a line that I wouldn’t want someone to do to me. I don’t want someone blowing up my personal phone every time something happens at my work, whether I was even involved or not, but especially if I was not involved at all.
