what all you say to the principal - more importantly.....Did your doctor give you a letter or note stating that you MUST work on a limited schedule?
Do NOT just give that letter to the principal - be sure you have more than one copy for your own files and uses....
If you can at least work part time with some flexible hours while this all being sorted out that would be good.
As for giving them a copy of medical explanations on your condition[s] Do not do that - any and all elaboration of your medical condition should be from your doc[s] to the HR reps for your school system. Let THEM do the looking!
Copying off explanations and giving them to family and friends is one thing...as they have to know and understand you are living with a CHRONIC condition. Employers will 'let you go' quick as a bunny if they REALLY understood - get my drift?
Hopefully you are near a large metro area that has attorneys who specialize in dealing with this all...one who can outline your options and any time restraints/constraints there could be in terms of the laws...
There is a LOT of paper, medical reports, diagnoses etc that go with this all.
Some docs charge for copies, others do not [I've found I can get copies of my records-I ask for them at least every year - and then fill in the blanks of the other doc records as needed - it's much cheaper that way] Some medical offices can charge $5. a page for the 'labor' and 'handling' to get you your copies...
I just think that talking to a lawyer about your options, well, it could be cheaper in the long run to know what info you need to get, and what it all could cost...I sure wish I could be of more help tho!
