Keep Current Hybrid Schedule

Pros

It would be a pro to leave the current hybrid schedule alone. For everyone’s mental health.

Cons

Moving to a 4:1 work model come September. They claim for collaboration. Half the time people sit on Google meets in their own department instead of getting a conference room. Plus when we try to collaborate in the office on the floor we’re told we’re too loud. Go figure.
