These spaces cannot be fitted with fully private office space per each individual and plexiglass guards and floor marking aren’t going to solve shit. Communal food areas have to stay closed.

Simply put, there has to be a medical basis for unequivocal treatment or immunity. Nothing prior to that could allow a path for these types of work spaces.
