Sorry to see you go..
Desdi,
Sorry to see you go. I had the same conversation with my family.
The lady at the leaving desk is very helpful and will answer all your questions. Make a list of them before you go there so you don't forget any. Arrive early so you can grab a number the leaving line gets long by mid morning. This is what she told me about a few of my questions.
Education- You will owe the company the remainder of the term your kids did not attend. e.g. If your last day is October 10th you will owe the company the tuition from Oct-11 through the end of the term. So best to have a leave date at end of term.
Housing Allowance- Will be prorated against the amount you used.
They will subtract your basic salary for every day shy of the three months you served.
EK will give you the 3 days off before your last day to pack up your house and get it shipped. (Not sure if that only applies if you give 3 months.) If in company housing you must be out by your last day. Conversely your allowance is figured to your last day.
The sooner you let them know the better.
Hope this helps. Glad you made it out alive.
