At my current company, if an employee leave and come back, they'll keep the same OID in Entra but they'll get a new `sub` in Google workspace. We had to put in place a process to be able to use an internal tool that used the login with Google.

That's most likely dependant on how the IT department handled the deprovisioning/provisioning of users in our Google Workspace, I unfortunately don't have the details for that.
