  Workplace bias creates negative psychological outcomes for employees,
permeating the larger organization. Workplace meetings are frequent, making
them a key context where bias may occur. Video conferencing (VC) is an
increasingly common medium for workplace meetings; we therefore investigated
how VC tools contribute to increasing or reducing bias in meetings. Through a
semi-structured interview study with 22 professionals, we found that VC
features push meeting leaders to exercise control over various meeting
parameters, giving leaders an outsized role in affecting bias. We demonstrate
this with respect to four core VC features -- user tiles, raise hand,
text-based chat, and meeting recording -- and recommend employing at least one
of two mechanisms for mitigating bias in VC meetings -- 1) transferring control
from meeting leaders to technical systems or other attendees and 2) helping
meeting leaders better exercise the control they do wield.
