Not Giving My Releiving Letter Or Experience Letter

I worked with a MNC for almost 10 months. I got better opportunity with our MNC. So, as per my offer letter Annexure II

Notice Period / Termination: This contract of employment between you and the Company may be terminated by either party by giving 45 days’ notice or gross monthly salary in lieu thereof.
On termination of this contract, you will immediately give up to the Company before you are relieved all correspondence, specifications, formula e, books, documents, computer code, literature, market data, etc. belonging to the company or relating to company's or their customers business and shall not make copies in any form.

In the event that you leave our employment within 12 months, you will fully reimburse the joining bonus, notice paid and relocation expenses, if any.

So, I resigned by stating that I am buying out my notice period on 6th May 2010 by giving my April's full salary.

There one more clause in my offer letter.

Company Policy: The Company at its discretion has rights to introduce new and amend existing rules and regulations at any time without prior notice. The employee will abide by new rules and regulations at all times without any prejudice.

Now, they are not relieving me...

What should I do....Help Me.

Dear Vinod,

The contents are almost every company will have the same structure of rules and regulations, there is nothing to do with other contents. Hence you may ensure whether the salary equivalent to 45 days is retained by the Company or not. If so, you can talk to the HR manager to give the relieving letter if not experience letter. If the HR manager reluctant to do so, see that there may be higher officials in hierarchy to whom you may approach.

Your issue will be cleared at once.

However, you may also kindly note that usually for such short term employment the employers declines to give any experience certificate. You can convince your new employer to that effect. As they are also MNCs they can understand the problem being faced by you.

But ensure that your notice has some acknowledgement. While leaving the office you may also send/handover in person one more letter referring the initial notice, 45 days salary deposit, handing over charge etc., and request them of issuing a Relieving letter and experience certificate and mention your postal address clearly to receive any correspondence in the matter. Dont forget to obtain acknowledgement of this letter.

You may also see that the entire episode should pass through in a smooth manner. If anybody is not responding positively dont take it as a serious issue. If they dont respond, you just do whatever talked above. Nothing will go wrong.

all the best.

They are creating problems stating that work till May end & take your relieving letter otherwise we are absconding you.
From my end I tried to compromise by telling that if you need i can manage 1 week i.e 10th - 14th May 2010 of work.
But my project manager insisted to work atleast 2-3 weeks.
What should I do?
Help Me...

Dear Vinod,
You may ask your new employer to give one month time since your present employer is requesting to stay back for another 3 weeks. If the new employer agrees for the same it is OK. Otherwise ask new employer to not to insist for the either reliving letter or the Experience Certificate. Then you can shoot a letter as I explained to you earlier and left the organisation. However, you kindly preserve the acknowledgement of the same.
I hope you understood the central idea of my advise.
