I found this OpEd by Joy Carter and Gill Evans in The Guardian in which they argue that investing in staff pays dividends in satisfying students and engaging them in learning:

“What we need to recognise in all of this is that there is a fundamental link between staff wellbeing and student satisfaction: engaged, committed staff will be those whose enthusiasm for their subject and their job shines through and rubs off on students. A balance needs to be struck. Student satisfaction and staff satisfaction are likely to improve together if providers recognise that balance and don’t seek to widen what can be a toxic dichotomy between staff and student needs.”
