There was an article published in Nature last week about bullying in science. In several of the cases mentioned in the article, funding agencies revoked funds from the scientists accused of bullying (after they were investigated, of course). This sends a strong message that these funding agencies will not tolerate this type of inappropriate conduct.
It’s also mentioned that 40% of academics have witnessed or heard about bullying happening to other people within the past year. This seems outrageously high to me. Of course, there is some grey area about what exactly constitutes “bullying” so everyone may be defining it a bit differently, but that doesn’t change the fact that there is clearly a bullying problem in academia. I think it’s important for institutions (universities, funding agencies, etc) to have very clear policies against bullying, which includes a clear definition of what they consider bullying, in order to stop this kind of behavior.
