Looking at your birth chart, we see that you are in the main period of Venus and sub period of Venus. Venus is in Taurus in your 10th house of career, recognition and fame. Career in teaching comes through Jupiter and Mercury. In your birth chart, Jupiter is conjoined with Debilitated Mercury in the 8th house, indicating a very strong possibility of relocation. Do remember that like you said relocation with half salary going into expenses suggests pressure. In such a case, you may accept the offer only as a stepping stone while actively applying for better opportunities. Do not remain stuck. Continue your search with patience and faith. Remember this is not your final destination, just a step forward in the right direction.
