This is exactly what happened at the school of my parents in law this week. One teacher (my oldest son's) applied to get in the public system long ago. She asked for the afternoon schedule. Last Friday they called her: you have been assigned (nombrado) to the morning schedule, you have to start on Monday. She asked if the could give her two weeks to finish her job at my in laws school at least a little decent. Answer: no, we expect you on Monday.
What a country...
We have lost 6 teachers this year to the public system. Same thing, phone one day, gone the next or very soon. In a couple of cases , not a big loss, but in others definitely harder to find capable replacements. We dropped high school for this very reason. Medina wants to do away with private schools. The PLD is trying to do a slow motion, Bolivarian revolution, to the country. Dominicans are stupid enough to let it happen.
Our new policy, if you apply and pass the government exams, off you go, we don't want you anymore. The govern is in fact allowing other professions to apply and take the exams. We have had one former accountant, and one current accountant both take the tests, pass, and are now teaching math in local public high school. One, will do very well, both her parents are teachers in the public system, and they happen to be good teachers and even better people.
