A teacher in the United States is facing termination after footage emerged of her breathing in a student's face.
The unnamed teacher, from Mead Middle School in Houston, Texas, was removed from the classroom after video of the September 17 incident was posted to Facebook.
The video, shared by local "community reporter" Grizzy's Hood News Exclusive, showed the teacher arguing with a student, who was backed up against a wall.
The mask-wearing student asked the teacher, who had her mask pulled down to her chin, to "get out of my face".
"You get out of mine," the teacher responded before she began exhaling heavily just centimetres away from the student's face.
People slammed the Facebook footage online, claiming it was "unprofessional" and "inappropriate".
School authorities have now confirmed the teacher involved in the incident is facing possible termination.
"After being notified of the incident, the teacher was removed from the classroom and an investigation was conducted," Aldine Independent School District spokeswoman told Daily Mail.
"The investigation has concluded and the district will take appropriate administrative action."
Mask rules have proved contentious in Texas, with Governor Greg Abbott banning mask mandates in schools in May, the Texas Tribune reports.
The ban stated that "no student, teacher, parent, or other staff member or visitor may be required to wear a face covering".
"The Lone Star State continues to defeat Covid-19 through the use of widely-available vaccines, antibody therapeutic drugs, and safe practices utilised by Texans in our communities," Mr Abbott said in a statement.
"We can continue to mitigate Covid-19 while defending Texans' liberty to choose whether or not they mask up."
But several school districts, including Aldine Independent School District, objected to the ban and have received approval from a Texas court to enforce a mask mandate in schools.
