With different health protocols in place and concerns about the transmissible nature of the coronavirus, the number of available substitutes that have the credentials to fill in on a daily basis are way down. âUsually we advertise through our website or the Banner and on our social media,â said Gloria Cahill, the human resources coordinator at the Southwest Vermont Supervisory Union. âWe put it out there that we need subs for teachers, paraprofessionals, nurses, custodians and office staff. Weâre always looking for subs, so we put in an ad every month and a half or so.â
