I have resigned from a company and have accepted a role starting October 1st. I had a discussion with HR, and they informed me that I cannot resign until my resignation has been accepted. Additionally, I will not be able to leave until a replacement is found and knowledge transfer is completed. I am planning to submit an immediate resignation letter, indicating that I am resigning without requiring any documents from the company as I am transitioning to a different domain. Could you please advise if my actions are appropriate?
