A gym teacher in New York was fired for playing the online video game Fortnite with two of his students last March.
He says he did it as a reward to encourage them to do better in class, asked them to get permission from their parents first, and only played for 20 minutes.
But the New York City School District said it was inappropriate internet conduct.
Some people in the gaming community are defending him.
This is the more typical response to kids playing Fortnite. Two brothers in the UK were busted by a teacher last March for playing Fortnite in a school classroom, and she was not happy.
