Leadership is nonexistent; the company is poorly run; there is zero transparency about any important decisions being made; some departments (marketing) and individuals (certain high-selling marketers) are favored; a incredibly unprofessional CEO who leads through intimidation.
The negatives about Hanover lie in its leadership. The director of the research department should be replaced. There is no transparency about any company decisions. Additionally, as an employee there I had reason to believe that the marketing team falsely advertised the research team's services: I once sat in a meeting in which a marketer spoke to us about how our research capabilities are described to prospective members, and told us that he markets the team as containing individuals with MBAs and PhD's. A researcher raised their hand to ask whether, indeed, there are MBAs and PhD's on the research team - there aren't, of course; just a bunch of 22-year-olds and Google. The research they produce is fine and works well for the members, but the company's services should not be falsely advertised just so that the marketers can make a buck. (Furthermore, the marketing team is higher paid - with many more opportunities to earn bonuses - than the researchers who are actually producing the product being sold. This is a large part of the perception, accurate in my opinion, that marketers are favored at this company.)
