english teacher mysteriously left halfway through the year. rumors went around that she was messaging students outside of school. never confirmed for me. also freshman year our econ teacher married the gym teacher and she left over the summer to teach at another school
Similar thing happened at mine. Teacher was suddenly gone. Had previously won statewide awards for teaching.
Found out that it was from an inappropriate relationship complaint so they canned him. Found out much later that it was all one-sided, emails and texts showed he was telling her to stop. We lost a good teacher.
