Paying people to leave actually sounds like quite a good idea to me.
Pay people 3 months salary to leave; don't pay new employees for the first 3 months.
It's much easier to identify an underperforming existing employee than to pick the best potential employee at interview. Not paying newbies filters out people who aren't motivated.
You would get few applicants for teaching positions with no pay to start. Teachers have to have degrees and teaching certificates which can be very expensive and given the current state of education many teachers enter the profession with student loans to pay off. An additional problem is that it's becoming increasingly difficult to gain employment as a teacher due to funding cuts and fewer teachers retiring among other factors. A result of this is that it looks like having a masters degree will end up being a requirement for teachers to keep their jobs, or to enter the profession. Being that teachers pay is not comparable to other professions with similar education requirements I don't see how this could possibly help.
