Bullying from the top

Some numbers from the Nature 2019 graduate survey (https://www.nature.com/articles/d41586-019-03535-y) are discomforting. Very few of the respondents were from Finland, and therefore the aggregate from Finland has to be taken with a grain of salt. But every single incidence is one incidence too much. What worries me most is a) that bullied PhD students in Finland feel that they cannot speak out about their experiences without repercussions, and b) that bullying from the top might be more prominent in Finland as opposed to bulling from peers (if one includes other academic staff into the "top"). One student reportedly experienced bullying from the programme director (which falls under "other", which was not separately listed by Nature in the graph). Numbers do not add up to 100% due to rounding and multiple mentionings.
