Hold supervisors accountable for their PhD students' welfare. Put in place mentor training that takes into account issues of being a foreign national, and the toxic culture in academia. Give awards to profs/students that advocate and create change around mental health.

Policies need to be put in place for postdoc working conditions, e.g. regulation of teaching and supervision obligations... I'm still just a postdoc on a fixed-term contract, but I'm supervising staff/students and running 3 projects to the same level as my tenured colleagues. So... the university gets my grant overhead money, and don't have to pay me a penny or offer me anything permanent.

Be aware of the stresses that the graduate students are under, and don't assume that because they're doing a good job of handling the work they have, that they are automatically able to take up additional projects.

I think the organizations in academia are already doing their best. The problem is the overall academic culture: how progress is evaluated at a global scale and the little government funding available.

The culture needs to change. The expectation that everyone needs to be constantly working, no matter what is incredibly damaging. Publications need to not be the only metric of success.

Value impact, not impact factor. Realise that pressure and exploitation don't lead to the best science. Value people holistically and not just as data producers. Abolish the old boys club.
