This article mentioned in the Times Higher last week had the headline Do some overtime (but not too much)
It is based on this article:
Fontinha, R., Easton, S., & Van Laar, D. (2019) ‘Overtime and quality of working life in academics and nonacademics: The role of perceived work-life balance.’ International Journal of Stress Management, 26(2), 173-183
which used a sample of 1,474 academic and 1,953 non-academic staff working for 9 higher education institutions. Key factors were the amount of perceived control over work and levels of job satisfaction. There is an open-access version of the article here.
