First of all, a written letter tendering resignation from the service of the company keeping in mind the span of Notice period, must be submitted to the Competent Authority and that letter must have acknowledgement by appropriate receiving staff. This is very important as there is no documentary evidence in 'verbal acceptance'. In the second stage - after completion of the Notice period, please hand over all the documents and gadgets like Laptop, Sim Card etc. to your immediate Superior with acknowledgement (make a list in duplicate which will retained by either party). Now the third part is - if you do not get the Release letter from the company after the stipulated Notice period, you do not continue your employment and send a Registered letter to the appropriate authority that ' As per the Order of the Hon'ble Supreme Court of India, I am deemed to be released from the service of the Company as there is no communication from the company beyond 30 days from the date of submission of my letter of resignation'. After that you can join new company citing the accepted letter of resignation and subsequent letter. Hon'ble Court has clearly stated in that case that vindication on the part of an employer cannot be a bar on an employee to join another organisation. The only exemption is if an employee is charged with moral tarpitude and Charge Sheeted/ Domestic Enquiry pending / Court Case pending in relation to service matters, then only the onus is on the employer to prevent an employee to leave. Otherwise OK. Thanks you and have a new service life.
