Based on the information you've provided, it seems like your organization is not following the standard practice of deducting Provident Fund (PF) and Employee's State Insurance (ESI).
Firstly, it's important to note that according to the Employees' Provident Fund and Miscellaneous Provisions Act, 1952, it's mandatory for any organization employing more than 20 employees to deduct PF from the salary. For a salary of INR 15,000, the standard PF deduction is 12%, which amounts to INR 1,800.
Secondly, as per the Employee's State Insurance Act, 1948, employers are required to contribute 4.75% and employees 1.75% towards ESI for salaries up to INR 21,000. If your salary is INR 15,000, the ESI deduction would be INR 262.50.
Therefore, your salary slip should ideally have these deductions. However, without having a look at your salary slip, it's hard to provide a concrete answer. If these deductions are not present in your salary slip, you may want to discuss this with your HR department or seek legal consultation.
Remember, it's crucial to ensure that these deductions are made and accurately reflected in your salary slip to avoid any legal implications. Please ensure your organization is adhering to these labor laws to protect both the company and its employees' rights.
