Miguel Monkc / Postdocs under pressure / Nature

A combination of long hours, stress and uncertainty over professional outlook can pose a significant threat to mental health. Miguel Monkc created this illustration for Nature’s first survey of postdoctoral researchers around the world. The illustration features the bullying, discrimination and pressure to produce that many postdocs face at work. Some of these issues are making many consider quitting science.
