Administrators at the Riverhead Charter School tried to bust its teachers union, pressed staff to dismantle the group and fired three employees because of their loyalty to it, according to two complaints filed with a state employment board.
School officials denied the allegations.
Raymond Ankrum, the Calverton school's principal, said he is "indifferent" to the union and that he never tried to dissolve it.
The first "improper practice charge," filed in February by New York State United Teachers with the Public Employment Relations Board, describes a climate of intimidation at the school.
It alleges that the school hosted an on-campus meeting Dec. 6 asking teachers how they felt about the local union. Jaclyn Scoglio-Walsh, a teacher and clinical social worker who had taught there for more than six years, spoke up in favor of the chapter, saying it was a good resource for teachers who need to file grievances.
She was fired two weeks later, with school administrators saying she used her cellphone during work hours, the complaint said. The complaint notes that cellphone use is permitted at the school as part of a policy established in 2013 to address student behavior.
Ankrum acknowledged the program, but said the teacher's phone use did not match up with entries to the system about students.
NYSUT filed a second improper practice charge March 27 concerning the termination of two more teachers.
One was fired in February after having spoken favorably about the union at a January staff meeting and another was let go in March after refusing to sign an anti-union petition presented to him by an administrator, the filing said.
The first improper practice charge is scheduled for a May 7 conference. If the parties involved cannot reach a voluntary resolution, a formal hearing before an administrative law judge would be held, and the judge would issue a decision.
The employment relations board has not formally accepted NYSUT's second filing, so it has not been assigned to an administrative law judge.
Scoglio-Walsh, who was teaching fifth grade when she was fired, wants to be reinstated. She earned $47,000 per year, she said.She said she wishes to be back in her classroom. She and her husband don't have children, she said, so her students were like family.
Scoglio-Walsh said she spent months in each of the past several years choreographing school productions -- time for which she was not paid. In spring 2011, students donned zombie makeup and tattered clothing for a "Thriller" routine inspired by Michael Jackson's classic 1980s hit.
