Yes, you’re quite correct about that. We recently did an analysis of whether employers can require verification of vaccination (see the link below).

Basically, all indoor workers need to keep their masks on where they can’t maintain 6 ft/2 m of physical distance. Hope this helps and check the linked piece below for more details.
