you have served 26 days notice period 

2) you have to pay salary in lieu of notice period for shortfall of 4 days only 

They can’t withold your experience certificate, saying that you did not serve the notice period. If at all there was any notice period, it is wrong for them to apply the same in your case as there is no mention of the notice period in your offer letter 

send them a legal notice in this matter, Calling upon them to forthwith release your experience certificate.

11. The terms of job including notice service or notice pay must be mentioned in clear language in the job contract.

2. if nothing was there there then after so many years the employer can not make such changes unless the employees agree to it with express terms.

3. n your case sending of email has not made a binding agreement and since there was no consent on your part it was not to be considered as accepted.

4. So the demand of the employer is unjustified and without any basis of law and you can ignore this demand.

5 However the problem lies in their refusal to give experience certificate which you can show to your nee employer through other documents like email communications and your joining letter.

If you have accepted the condition of one month notice with the company then you have to serve the same. If not served they may deny you experience certificate. You can pay basic salary for period you have not served

See if it was not in offer letter then company cannot force you to serve same issue a legal notice to the company for releasing full and final point and experience letter.

E mail is one sided proposal and until acceptance is not given, dose not complete the contract hence,not effective. You can approach labor court for to release experience certificate

Dear Client,

Your joining letter is enough for you for getting a job in another organization. 

- As per law, the notice period completion is not mandatory , and the organization is bound to issue Experience Certificate .

- Since, there was no clause for notice period , hence you are not bound to compelete the same for leaving that organization as well.

- For agreement , acceptance should be there . Only sending a massage via emai , the organization cannot bind you for acceptance its new clause.

- Better , issue a notice/complaint letter to the organisation after narrating all the details and ask for issue of experience certificate, and further warned that you are going to take legal action against the concerned official.

Hello 

If they are harassing you like this then please go ahead and file a complaint before the Labor Commissioner.  

You yourself may do the same and you do not need a lawyer to present the case before the Labor Commissioner. 

Regards 

The terms of the contract were changed after you joined. But still they are demanding a month's salary in lieu of the experience certificate.

You should explain your situation to the company. Anyways if they don't give you an experience certificate you should give them a legal notice.

Regards 

It is a general rule applicable to all employees that they should give one month notice before leaving a job. Hence, even if such condition is not mentioned in the appointment letter, you are bound to give one month notice or to pay a salary of one month. 

You applied for NOC or resignation letter ??

If you have given notice period for one month and skipped only 4 days then you are liable only for paying salary of 4 days not for one month. 

Ignorance of law cannot be claimed as an excuse.

Your company has informed you well in advance about the notice period, you cannot blame the company about it if you have not viewed the company mails.

You may have to comply with the company's demand if you require the experience certificate, however you may negotiate with the company for 15 days salary as compensation, if the company permit you.
