My company is not relieving .

There is no any such things mention in writtenly that NP is mandatory and yet I have not send him Signed Copy of Appointment letter and I am in 

probation Is it make me in trouble to boarding in any Company .

If notice period does not apply why have you offered to tender notice pay?Did you get copy of his mail to HR and record his threats to blacklist? Are you a member of employees/trade unions? You are in which state? Make good relationship with HR of next employer. If they want nothing will happen to you. Lodge complaint thru unions/lawyer.

please Assist further for this case .

If you have any solution ...

1. You need not require any releiving letter becasue you were not on rolls of your previous employer. If you have already joined the M.N.C. and are on probation and this new employer does not insist that you should produce the releving letter then why should you bother about the threats that you are getting from the manager under whom you used to work with your previous employer.

2. Send a legal notice through an advocate to such mamanger cautioning  him to refrain from giving you threats of defaming you publicly on electronic media and if he does so then you will file a criminal defaation case against him. 

3. Just take care and perform well with best of your skills till your probation period with the M.N.C. ends. Make a good rappo with your new employer. 

4. Just relax and avoid receving calls or replying or talking to that manager. He cannot do anything that will hamper your employment with your new M.N.C. employers.

Record all threats/calls (audio/visual/witnessed- etc). Obtain copy of manager's mail to HR. Become member of unions. Are you a member of NSR and did you give PIN to manager? The unions and lawyer wou know how to handle your matter.

thanks rohit for such great support .......

No i am not member of NSR and dosent given any such PIN no. to my manager kumar .

Do you have copy of Manager's mail to HR?

Record all threats?

Once you have these, approach IT/ITeS employee's unions, Trade Union leaders, labor Law Consultant and then Dept. of Labor Officials and other forums as suggested by your counsel.
