My customer is a religious association, that want's to certify their own building.
The building is only used on Saturday by the members of the assotiation. There are no FTEs.
Is it enough to survey all members only for that one day of the week.
As all occupants are visitors I can't ask for days of absence, compressed workweek, etc.
I will only ask for how they got there on that single day.
Is that the right way?
