Dear Parimala,
Your query is more on the closeness of the office rather than the actual problem that you are someone else is facing. The replies to your questions are as below:
Q. Is it legal for a registered company working without a physical office premise?
A. Because of the pandemic, a large number of companies are running their operations by telling the employees to work from home (WFH). However, to register a company, there has to be an official address. You may check the company's website.
By the way, what about the appointment letter issued to the employee? The company's address must have been mentioned in the appointment letter.
Q. What legal action can be taken against the company for running the company without having the registered office?
A. I don't think this contingency will come at all. You may check Google and you will get the address of the registered office. As stated above, you may check the company's website or the appointment letter.
Q. How an employee take legal action against the company on a full and final settlement issue when the physical office is closed?
A. Method of operation of the company and Full and Final Settlement (FFS) are the two separate things. Why these are linked together is not understood. The business owner or the employees may work from home but that is not a ground to hold exited employee's FFS. Wherever the owner is working, you may obtain the address of the company from Google or from the appointment letter itself and send the official letter in the form of hard copy for the clearance of FFS. Send the letter by Speed Post with acknowledgement due. Scan the copy of the letter including the receipt from the post office and send it by mail too. Preserve the printout of the email. If you do not receive any reply or the FFS then you may file a complaint in the Labour Office under whose jurisdiction your company falls into. Once you file a complaint then we will guide you on what to do further.
Final comments: - Suppose the business owner has done a business without registering his/her company or has not registered under the Shops and Establishment Act, even then also an employee needs to have tangible proof of employment. A complaint can be filed in the labour office for undertaking a business venture without following a due process of law. Nevertheless, whether someone follows the law or not, I recommend you restrict your attention to the recovery of the dues.
Thanks,
