I have worked in a new startup firm as a sales trainee. I have worked there for only 4 days during my probation period. Now, I want to resign from there due to certain personal problems. I had no bond with the company. I have sent an email to HR regarding my resignation, and they have forwarded me a mail regarding my final settlement amount. I have returned all company properties that were in my possession. The only document I signed was my offer letter at the time of joining. Can the company take any legal action against me? Please guide me on this issue.
