Do they really not have "Gossipers"?

As part of the analysis of the business, I returned yet again to be a type of "secret shopper".  By that I mean, I had casual conversations with employees in the parking lots, the gift shop, in the fields and prompted some difficult conversations.  I talked about the economy, working conditions, the "owners", and I could not find a gossiper in the group. I even went as far as speaking to a person I know as an employee who would trust me that I would not provide evidence of who they were.....but nothing, no negative experiences or stories.  Can an organization really have a satisfied group of employees who have such a strong positive and productive working relationship with nothing negative to say?  (Only terrific stories about the farm, the family, the tradition and the quality.)
