How Professors Spend their Time

In an article in The Blue Review, John Ziker explores how "Homo academicus" at Boise State University spends his or her time: https://thebluereview.org/faculty-time-allocation/

An excerpt:
"The most surprising finding of our analysis of practices was that faculty spent approximately 17 percent of their workweek days in meetings... Thirteen percent of the day was spent on email... Thus, 30 percent of faculty time was spent on activities that are not traditionally thought of as part of the life of an academic. Twelve percent of the day was spent on instruction... and an equal amount of time was spent on class preparation. Eleven percent of the day was spent on course administration... Thus, 35 percent of workweek days was spent on activities traditionally thought of as teaching. Only three percent of our workweek day was spent on primary research and two percent on manuscript writing."
