If a hybrid team does not solve the problem articulated here, this workplace will ultimately fail, as it creates a two-tier workplace with remote workers becoming secondclass employees.
If you are not ready to cut the physical office umbilical cord and insist on a hybrid scenario this issue is solvable with one simple policy:
“If one person is on screen, everyone is on screen”
Meaning, if you are going to have a meeting where even just one person is remote, then everyone who is co-located must also be on screen.
This ensures that everyone has an equal seat at the table.
