At my school, I have found that the principal and the secretary give preferential treatment to this one teacher but not so much to me. Here is what happened recently. Teacher X had a senior female student who apparently blew up and got angry in her class. I also have this female senior in my class, and she has been calm and never got angry. Because Teacher X reported this senior's outburst, the student has been suspended from school except for major tests and major school events that require her attendance. So the principal and secretary strongly took the side of Teacher X. On the other hand, I have another female senior, who is frequently in a bad mood and gets angry about different sorts of things in my classroom. This senior took her cell phone to the bathroom for 20 minutes before returning, and I caught her reading personal emails during class time on her computer. On both occasions when I confronted this student with her rule-breaking behavior, SHE got mad at ME, not the reverse. On the second occasion, this senior stormed out of my classroom to complain about me. When I told the principal about this he said that he "would look into the matter." He didn't vote for immediate suspension of the student as he had with Teacher X, so instead of immediately siding with me, he needs to investigate. And the secretary didn't tell the angry student to shut up and go back to class, but she let the student skip part of my class to "cool down." Should I point out this discrepancy and double-standard to the principal or just keep quiet? I am probably just going to keep quiet, but I would like to hear responses. Should I tell the secretary that she should not indulge student temper tantrums but she should discipline the students instead of letting them skip class to "cool down"?
