My wife works in a private school, while joining they asked her to submit original certificate. As per offer letter she has to serve 3 months notice period.
After few months started working she become ill in the school campus, so they called me took her to the hospital. After reaching me in the hospital they left (i paid all the hospital expanses).
Next day she tried to inform in the school they she was not able to come as she is not well, however not one picked her call.
Then next day she went school and took the classes. in lunch time she was taking to her mom as she was asking about her health, in between school principle came and started shouting (without asking how is your health now), took her to the third floor (even though my wife was not well) as started shouting in front of her school staff.
Then next day she reigned and was ready to serve the notice period.
After reign they started holding the salary (they are holding one and half month salary)
After some time took vacation (approve by principle prior to this issue) then went home and there she become ill.
so she informed in the school that she was not able to come to school about 10-15 as doctor had asked to take 10 -15 days bed-rest.
Before going for vacation she served 1 month notice period.
After getting fit she went to school to rejoin however principle (verbally) asked her to go back (without giving any letter).
The i have asked my wife to go back to school and ask principle to give the letter (but principle denies to give any king of letter).However my wife was ready to serve the notice period.
Then my wife has asked them to return the original certificate. but principle said you have pay three month salary (event after school is holding one and half month salary and she serve one month notice period).
Since OCT 2015 they are holding my wife original certificates.
She went to school may time to get her certificate but they are not giving even they are read to meet.
We have all the conversation recording with us.
Is there any legal law permit file to complaint against superior?
What is the procedure to recover original certificate?
Please advise me how to proceed further.
