Hello,
You haven't given some basic details.
1] Is this your First Job?
2] Do you have any Bond? If Yes, for what duration?
3] Why don't you want to serve the Notice Period? When you joined the Company, I am sure you would have been aware of this aspect.
4] It's surprising that you didn't SEEM to have discussed your resignation with your boss--any reason(s)?
5] You take umbrage in the fact that it wasn't mentioned in your Offer Letter that you need to take your boss's OK for the resignation to be processed by the Company. But you DON'T want to follow the other points/clauses in the very same Offer Letter--meaning you wish to be CHOOSY?
Unfortunately, things don't work this way in any company. Like Atul Khanna mentioned, what about your Work responsibilities? And also, what about the work ethics & the Company's interests?
Frankly, I think you have to blame YOURSELF for this situation. I can see only 2 options:
1] Talk to your Boss & HR to resolve the issue.
2] If not, take back your resignation & rejoin. Look for other opportunities--and next time you want to resign, better be more careful & PROFESSIONAL.
Also, since you have ~2 yrs exp, it will surely be tough for you to explain any lack of employment records later in your career--if not immediately, it COULD much later too, when it would be too late. Just use the 'Research' facility @ the top of this page--you will find dozens of postings of those who faced such problems.
All the Best.
Rgds,
