Legal Advice Needed: Employer Not Providing Offer Letter, Employment Agreement, or Salary After Joining

Hello, I joined a company on August 5th, 2024, but I have not received my offer letter, appointment letter, or a copy of the employment agreement. I was asked to sign the employment agreement, but the company did not provide me with a copy of it, either digitally or physically. It has been over a month since I started working, and these documents are still pending. Additionally, I'm concerned that they may refuse to acknowledge me as their employee and might not pay my salary. However, I do have evidence to prove my employment with the company, such as: - Official email with company's domain - Emails sent from the company’s official email ID. - Leave information email I sent to my manager. - A SIM card provided by the company for work purposes. - WhatsApp chats with the company’s HR and clients that I’ve been asked to handle. What are my legal rights in this situation, and what steps should I take to ensure that I receive these documents and my salary? Is there a legal way to enforce my rights if the company continues to be uncooperative? Thank you for your guidance.
