Bullying does not just occur at school, or in the workplace, or online. It can occur in many situations. (Note: Tim Field's website is called Bully Online, but that was because he wanted to put his insights online to help more people, rather than taking phone calls individually from people. The name of the site does not just refer to online bullying.)
In my experience it is not useful to dismiss claims of bullying without evaluating the situation carefully, clearly and without prejudice.
My experience is both as a target of bullying and as a Union delegate supporting others who have been bullied.
Yes, the other newer site is easier to navigate, but for me, finding Tim Field's site and realising that I was being bullied was a turning point in my situation. Yes, the senior manager who was the bully managed to take my job away from me, and yes I suffered mental, emotional and physical consequences from the experience, but when I recovered I felt more capable in recognising bullying and taking positive, proactive steps to deal with it, for myself and for others.
