| Dear Carolyn: How do I remove a colleague I don’t like and who doesn’t like me from a trip I planned, which another colleague invited her to? I teach high school and regularly invite my students to participate in travel opportunities. This fall, an unusual one presented itself with a generous subsidy, making this trip particularly appealing to both students and faculty. I invited a teacher whom I have long admired and wanted to become better friends with to attend. The first trip was incredible. Interest in a second, summer trip exploded across campus, and I quickly arranged to bring it to fruition. My colleague invited another teacher to chaperone with us. This teacher has been snarky to my face and behind my back, literally — I’ve heard her bad-mouthing me down the hallway to other teachers after one unpleasant exchange in which I asked for her help and she didn’t want to give it — and her general demeanor is unpredictable, brash and unpleasant. My chosen colleague knows I do not want the snarky teacher on the trip but hasn’t disinvited her. It’s awkward, and she’s hoping fluctuations in enrollment will eliminate the need for another chaperone without requiring a confrontation. That would be ideal but is an extremely unlikely scenario. Do I suck it up and allow the snarky teacher to come? Do I demand the colleague who made this move without my consent remove her? Do I confront the snarky teacher myself and disinvite her, knowing full well the fallout will be more backstabbing? — Cut the Snark |
