From keystroke loggers to screenshot-capturing software and webcam eye-trackers, employee-monitoring tools have been on the rise since the COVID-19 pandemic drove white collar workers out of their cubicles and into home offices.

The survey of 515 in-house lawyers, C-suite executives and HR professionals in the U.S. found 45% of companies are using them, but 41% are not and aren’t considering doing so. Twelve percent are considering adoption, and 1% have made the decision to adopt but haven’t yet done so.
