The Region 14 school district could hold a hearing next month on the proposed firing of the Superintendent over vaccine rollout.   Joseph Olzacki faced calls for his termination over accusations that teachers were initially passed over for COVID-19 vaccines earlier this year.  The Board of Education placed Olzacki on paid administrative leave over the winter and launched an investigation into the district’s rollout. Teachers had claimed administrators, central office staff, and school board members and their spouses were prioritized at a clinic in Southbury in January.  The board has finished its investigation and a hearing could be scheduled for early August, open to the public. Region 14 finance director Wayne McAllister has been serving as the interim superintendent since February.
