Professor Adam Alter's comments on how checking work emails can change an individual's level of productivity are cited
Excerpt from Ladders -- "Not all of the mistakes we all make in the first 10 minutes of the day are caused by procrastination. In fact, getting on with our work in the wrong way can have a negative impact on our productivity. Checking your work emails first thing is a common mistake. New York University’s Adam Alter says that it takes an average of 25 minutes to get back to being most productive after you’ve checked your emails."
