The Times Higher Education (THE) recently reported on a paper by Malcolm Tight, professor in Higher Education at Lancaster University's department of educational research.
The paper argues that there has been no substantial change in academic workloads in the UK - which average a hefty 55 hours a week - for nearly 15 years.
Professor Tight said: "On average, there simply is a limit to the number of hours a week people can and are prepared to work, and it has been reached."
