Report on Bullying and Harassment at Kingston University

Recently, a report was published on the filing of university bullying and harassment related grievances and their outcomes.  Interestingly, the report notes that in the three year period between 2007-2009, Kingston University had 12 such cases, nearly all of which were filed against superiors, and none of which were upheld.  This result raises some interesting questions:
 
1. Were all of the staff members filing bullying or harassment related grievances lying? 
2. Why were there relatively few cases lodged?  Was this because staff were aware of the fact that such grievances are rarely, if ever, upheld, and that filing such a grievance might result in disciplinary charges or other forms of detriment being perpetrated upon them?  Or was it because bullying and harassment are not really a major problem at Kingston University?
