Resigning on a cordial note due to pursuing higher studies, I'd like to resign in the middle of the month, and the notice period is two months. Manager says it may take a month or two for me to complete any existing work before I leave and he's agreed not to assign me any fresh work. But given the nature of the work to be completed (unpredictable bugs and a lot of debugging), I feel it may take two and a half months.
So would it be appropriate to write a resignation in the middle of the month stating that I'm resigning and would be serving the two month notice period but if I'm required to work for two and a half months, kindly consider the effective date of resignation to be at the end of this month?
Any pitfalls or precautions I should be aware of?
