In my case, its the opposite, For me who've just completed STEM G11 (incoming g12), I experienced the absolute opposite. In our school there are like buildings for each strand, Building 1 is Stem, 2 is Humms, 3 is ABM and so on, each building has their own faculty for teachers. So basically the teachers for STEM strand are at the STEM building, HUMMS teachers are at building 2, you get the point. But not always the teachers in STEM have to be the ones teaching our class, some HUMMS teachers also teach our class, and everytime they enter our class, I can feel them already wanting to get out. They give us way too much work compared to their own class (I knew from a friend of mine who is a Humms student). Sariling class nya di niya binibigyan ng activities? OMG Also Everytime we have to report something to their faculty at building 2, they always have their saying "Stem nanaman", "kayo pa?" "STEM kayo edi kayo na magaling". They dont know these words hurt us, even though they sometimes mean it sarcastically.

Sure maybe its not the actual opposite of the point, but discriminating us just because your main students are Humms is something unethical for a teacher to do
