Would a school actually lose 12 teachers over 3 students

My kids high school is going through something where 12 teachers are currently threatening to walk out if they don't expell(not suspend) expell these 3 students. These 3 kids are awful and their parents are horrendous. I almost fought ones mom because one of the girls was telling my daughter to kill herself because she's gay and the mom told me I shouldn't have raised a dyke. Everyone hates these kids. My sister is a para there and they have slashed a teachers tires. One hospitalized a teacher. They've jumped students to bully them. One lied about a teacher being a predator. She fully admitted she lied. The principal hasn't done much. I was up there because they were bullying my kid. One of my son's friends passed away last year and they were mocking it online. The final straw is a teacher quit. It was actually my son's civics teacher. These kids heard a rumor that this teacher was on Grindr. Cat fished him on Grindr, then outed him to the towns Facebook group. My sister has been filling me in but 12 teachers are like either expell them or we leave. I'm just worried because this is my daughters senior year. Losing at least 4 of her teachers will fuck her. Would the school actually choose to lose 3 students who don't care and their parents are awful over 12 teachers? I'm stressing so fucking much

Edit: I had been at that school. My daughter was cutting herself because the bullying was so bad and I was yelling at the principal because nothing was being done. Like I said, me and one of the moms almost fought over this shit. I'm not proud to admit it but I slapped her the second she called my daughter a dyke and we almost full on fought. I shouldn't have done that but I couldn't believe someone would say that
