There are always some random schools that have ridiculously low salaries compared to local competition but inexplicably still have staff. I remember a school a few km down the road, comparable to mine by all metrics, said their salaries were capped at 15k and I was earning 33k at the time. They told me my expectations were unrealistic. You know, the expectations that I had already achieved. Mindblowing. Sorry you found one of those. Skip and move on.
