Judging by the responses she had, it wouldn't be the last, she said.
"Our staff have a heightened awareness about bullying, thanks to the strong stand our management takes on this issue," Ms Cossey said.
"Bullying is not tolerated in our workplace, so if we can support the effort to stop it happening anywhere else in our community, we will do so.
"Bullying is a significant problem which impacts on people's mental health and wellbeing."
Ms Cossey said the health board staff wanted the community to know they supported the Mental Health Foundation's call to create workplaces, schools and communities where everyone felt safe, valued and respected, regardless of age, sex, gender identity, sexual orientation, ability, or cultural background. A number of other groups including the Women's Network, Jigsaw, and Supporting Families are also getting behind the cause.
