More than a quarter of 329 London workers surveyed admit they routinely take their laptop or other mobile computing device to bed to do work.
The same survey indicated that 57% of bedmates found it "a very annoying habit."
More than half of those who do work in bed did so for between two to six hours every week, according to the survey carried out by researchers hired by Credant Technologies.
Eight percent of the respondents also confessed to spending more time on their mobile devices during the evening than talking to their partners.
When asked the question, "What is the last thing you do before going to sleep?" 96% did say it was to kiss their partners goodnight. The remaining 4% (71% of whom were male, according to the survey) confessed to completing work and checking e-mail. (See "E-Mail Addiction: Five Signs You Need Help.")
According to the survey, more than half of the workers are routinely uploading and downloading sensitive corporate information to their mobile device while in bed, and most are using a wireless network, with a fifth admitting their network was not secure as they tapped away answering e-mail and other tasks.
Credant Technologies, a security firm making endpoint data-protection products, was inclined to scold in its statement about the survey's results.
In its list of five tips that included admonitions to use encryption, strong passwords and the like, the last tip was: "Finally, use your bedroom for what it's designed for. And if you're not feeling sleepy, your laptop is the last thing you should be turning to!"
