yes, hentak kaki at geo4 is really the worst, especially if you served through the 2022 salary revision and the recent increases to fresh grad teacher starting salaries. Your base salary will lag behind the high performing/high flyer geo3s for sure.

Worse still, it's harder to get a better perf grade at geo4 compared to at geo3 because the expectations are higher. So you're screwed in terms of base salary and screwed in terms of PB.
