The video was recorded in November 2013 at Oaktree Elementary in Goodrich and recently released to a TV station. Patrick Greenfelder, a lawyer for the boy's family, says the teacher, Nicole McVey, and Principal Michael Ellis taunted the 10-year-old student, who has Asperger's syndrome.
Ellis resigned. McVey opted to fight the district's attempt to fire her through the tenure process.
In a statement Friday, MEA official Abby Zarimba says an upcoming hearing will let the teacher "provide context and truth about the situation."
Greenfelder said "the video speaks for itself" and "clearly shows a lack of compassion" for the boy.
