What is the Islamic view on video calls between unrelated men and women for work?

A video call between unrelated men and women for legitimate work purposes is generally permitted by most contemporary scholars, provided the call stays professional, is limited to necessary work matters, and doesn't function as private, prolonged, unsupervised personal conversation — the concern scholars weigh is whether it constitutes khalwa (improper seclusion), which several contemporary fatwas note applies differently to a screen-mediated, often recorded/loggable professional call than to genuine physical private seclusion, though caution is still advised.

Scholars generally recommend: keeping calls purpose-focused and reasonably brief, avoiding calls that become personal/casual in nature, ideally involving other participants (a group call rather than strictly one-on-one) where the nature of the job allows it, and maintaining modest presentation on camera. Some more conservative scholars still treat a private one-on-one video call as functionally similar enough to khalwa to advise against it where avoidable, so this is genuinely an area with a range of scholarly caution levels rather than one uniform rule — readers in roles requiring frequent one-on-one video calls with colleagues of the opposite gender may want a specific ruling from a scholar familiar with modern workplace realities.
