I have two offers from two companies—let's say Company A and Company B. Company A has confirmed my joining date, and Company B may take another 4 to 5 months. I want to join Company A in the meantime, but my problem is if I join Company A and leave without serving the notice period to join Company B, will there be any problem with the PF UAN as it is already linked with PAN and Aadhar? Will there be any issue with Company B regarding PF? I am concerned because the UAN is already linked with Aadhar, making it impossible to create another one. So, what might Company B do in such a situation?
