bullying is subjective, whats bullying to some is not for others,
it appears they considered you over sensitive?
i had an employee who when asked to do a task, at her own speed but with accuracy thought i was bullying when after being presented with the work and noticing an obvious error on the first page asked her to re-do the task properly
she left, apparently because i kept asking her to work
personally i have always managed to apply myself well in work and tend to not get picked on if their is a bully about
