Overall, 54% of employees with personal email accounts say they at least occasionally check their personal inboxes while at work. Most do soon a daily basis; 39% of all personal emailers say they check their personal accounts at least once a day at work, while 15% report checking in less often than that. Just 7% admit to refreshing their personal inboxes at work constantly, and 4% say they check in several times an hour.

Some of the same groups who report the most frequent checking of work-related email are also the most likely to report frequent tending to their personal accounts while at work: higher-income workers and those tethered to a desk. Fully 66% of those in jobs earning $75,000 per year or more say they check their personal accounts at work, compared with just 45% of those in jobs earning less than $30,000 annually. Likewise, those in professional, managerial and clerical positions are more tuned into their personal email at work when compared with those working in the service industry, skilled and semi-skilled jobs.
