In your appointment letter ,the notice period is not mentioned during probation period.

Your employment contract is governed by terms of contract of appointment.

Did the employer issue any corrigendum to apointment letter.

Did the employer any other letter confirmng  completion of training period, and initiation of probation period and describing terms etc.Did you sign your acceptance of any adittional conditions.

Hope you  submitted  your resignation under acknowledgment, and have submitted the company property if any, under receipt.

And employer has not responded  to you in writing.

You may submit  a reminder to MD,CEO, HR Head, Company secretary,and ask for your acceptance letter, settlement of account,F&F,form16(if any TDs is deducted),work experience certificate,NOC,NDC,releiving letter etc.

Let the employer respond to you in writing.

You may act smart, be persuasive,and  resolve amicably with HR.

Or you can lodge greivanc with local labour concilliation officer.

Sir,

Other than this Appointment Letter, the Employer has not issued any other letter, nor I have signed on any document issued by the employer.

Director is your appointing authority.For training and probation there is no notice period.

So far the director or company has not levelled any allegations on you,they have simply asked to work for 1 month , verbally.

Don't be anxious or over react.Setlle the matter amicably.Be smart.

You can express that due to certain exigencies you are unable to continue.

However you would like to maintain the rapport and relationship, and you shall recommend suitable candidiate whenever you come across and also help the candidate and company whenever you can.

The term of appointment like "You shall obey the orders given by the seniors and diligentaly  carry out the same" is not one a highly professional and HR oriented company would make.

If you face any difficulty lodge your greivance with office labour commissioner.

The letter does not stipulate any notice period by either party. Hence submit a written resignation and leave the organization. No actio whatsoever can be taken by the Company. Ensure that you hand over any pending assignment and take an acknowledgement. If an acknowledgement is not given, confirm the hand over by a writtten document.
