Exposure to bullying behaviours and support from co-workers and supervisors: a three-way interaction and the effect on health and well-being.

These results indicate that the negative effect of workplace bullying on health and well-being is weaker if victims perceive that they have co-worker support, but this protective effect seems to be conditional on the perceived level of supervisor support. In other words, lack of supportive leadership may block the beneficial effect of perceived co-worker support.
