What is proper protocol for a teacher resigning mid year?

She is going against a contract she signed. So the school/governors are in their rights to take her to court.

I doubt they would though, it would just go against her on a reference.

schools are different. Two weeks is not enough. Can you find a fully qualified teacher for any subject within the middle of the year? all qualified candidates already have positions. The teachers contract spells out responsibilities and what to do if leaving.

We sign contracts for the entire year. Districts are lenient when it comes to legitimate reasons like moving, but have the power to petition the state to remove the credential for the length of the contract. Finding a "better opportunity" is not a good reason to leave the students without a teacher.

The district will most likely ask that the teacher stays until a replacement is found. If your friend will not be teaching any more and doesn't need the credential - then it doesn't matter. (although district lawyers might think of a few things - cost to advertise for a replacement, cost of substitutes - etc..)

It depends on the school and circumstances of the person.It depends on what is written in the contract.The person needs to read the fine print of her contract,the same applies with any jobs.
