Narrative: When I arrived at work for my XB00-XJ00 shift there was a CIC on the Supervisor desk. The area was still combined at the mid sector (XX) except for sector XY which sits 4 inches from sector XX. Sector XY was open and staffed by a Supervisor not wearing a face covering over any part of his face other than his neck. This Supervisor has been repeatedly told to do so; but most of the time doesn't do so. The adjacent airspace was ATC zero for a positive COVID case that had been reported the previous afternoon. This Supervisor often opens this sector between XA00 and XC00 am to avoid going to stand up and also avoid any sort of volume or complexity in the airspace. I understand normally it's not an issue besides that it's an awkward configuration that confuses everyone in and around the area; but today it was much more than that. Today marked ZZZ's X confirmed positive COVID case in X days' time and X [number] in X weeks. This supervisor not wearing a mask and opening the sector to get time was not only dangerous but just plain rude as the controllers sitting next to him were forced to work the other sectors while properly adhering to mask wearing guidance. I wish this was the end of this report however the day progressed to be even worse. During the morning the contingency plan was abandoned and we were told we could go through the sterilized airspace however far 'we felt comfortable.' In fact we were told it would be OK to give IFR clearances off the ground in the sterilized airspace as well. I don't think this is a safe idea. One person's comfort level could be more than a different person's. We don't know how far frequency coverage goes into the sterilized airspace and this could result in NORDO aircraft in conflict in the airspace with no way to resolve the confliction. To add further to this; later in the day a D-side trainee was brought to the area to give an over the shoulder for the resumption of training. 4 people were plugged in to one sector while the same Supervisor still wore his mask around his neck. This put 3 more controllers at risk unnecessarily during the middle of a facility outbreak. This D-side trainee is now fully certified again on all the area D-sides after working a total of 1 week in the past 7 months which presents even more risk both to proficiency and also to proper social distancing measures. After this certification was complete he was used throughout the day and told to 'pick a D-side' at the instruction of the Supervisor further combating any social distancing guidelines that have been set in place by state health officials; NATCA; and facility management.If this is how ZZZ center is going to continue to operate this is only the tip of the iceberg with how much crossing paths there is since the return of normal schedules and staffing. Supervisors do not need sector currency.




Synopsis: Center Controller reported a facility Supervisor continually does not follow state and NATCA guidelines regarding face mask policy.
