All non-union town of Provincetown employees will be required to be vaccinated for the COVID-19 virus as of Sept. 20, or show proof weekly of a negative test result, Town Manager Alex Morse announced at the Sept. 13 Select Board meeting. Negotiations are to be undertaken to bring about the same mandate with the two unions working in Town Hall as well, Morse said. The two unions cover some police department and public works department employees. The municipal mandate, implemented to protect public safety, is one of the first in Massachusetts, Morse said. The number of positive COVID cases in the last two weeks in Provincetown was six, based on state data from Sept. 16.
