A massive study of almost a quarter of a million US academics showed women are leaving academia at significantly higher rates than men.
They are also leaving for different reasons. While men are more likely to leave because they have been attracted by better opportunities, the number-one reason women cite for leaving is toxic workplaces.
I left academia exactly from these two reasons: toxic workplace and eventually a better opportunity
Their many years of post-secondary education, their training, their research – it all costs money. This money is wasted when they are pushed out of academia.
