That doesn't change anything. People have lost their jobs over smaller things. School is about teaching students and limiting distraction while having an authority figure students respect(which I doubt a lot of students do at this point). Academically inclined or not, a group of student's right to not be distracted usually trumps one teacher's job, and their complaints will likely be taken more seriously than the teacher herself. Schools are more worried about their kids and reputation than the teachers they have on their staff. They don't hire teachers so they'd have something to eat, they hire them for a specific set of skills and expectations that when compromised, are replaceable.
