Dear Riyasjmr,
If the statutory acts apply to your organization, then the rule states that a total of 6.5% (1.75% to be deducted from the employee and the remaining 4.75% to be contributed by the employer) of an employee's gross salary (provided the gross salary is <15000) is to be deposited by the employer in the ESIC office of that region. So, if your salary (gross) is Rs. 8887/-, then you need to contribute @1.75%, which is around Rs. 156, and only this amount is to be deducted from your gross salary regarding ESI deduction. The rest 4.75% of the gross is needed to be contributed by the company itself. They cannot deduct Rs. 391 because if your gross is around Rs. 22343, then only @1.75% it comes to Rs. 391. If your salary is above Rs. 15000, you will not be covered under the ESI Act. Please ask your HR department to provide a clear idea on this.
Similarly, you need to contribute 12% of your Basic+D.A (which is to be deducted from your gross) for PF, and a similar amount is to be contributed by the employer. Again, going by your post, it can be understood that if the company deducts Rs. 266, then your Basic + D.A is around Rs. 2216. Here, do check with your HR regarding the minimum wages of your region for a skilled worker, as PF is to be deducted from minimum wages.
