The standard should be ended.   There is no basis for keeping such a health and safety standard for all businesses in the Commonweath.  This standard was flawed as it assumed all businesses were the same.  If you have workstations that are 6 ft or more apart, and staff are immunized, the standard said masks are required.  The only carve out was if you were in a room alone.   There is no science to support that the immunized who are sitting 6 ft apart indoors must have a mask on unless they are in a room alone.
