Section 498A of the Indian Penal Code states the following:
"498A. Husband or relative of husband of a woman subjecting her to cruelty.—Whoever, being the husband or the relative of the husband of a woman, subjects such woman to cruelty shall be punished with imprisonment for a term which may extend to three years and shall also be liable to fine. Explanation.—For the purpose of this section, “cruelty” means—
(a) any willful conduct which is of such a nature as is likely to drive the woman to commit suicide or to cause grave injury or danger to life, limb or health (whether mental or physical) of the woman; or
(b) harassment of the woman where such harassment is with a view to coercing her or any person related to her to meet any unlawful demand for any property or valuable security or is on account of failure by her or any person related to her to meet such demand."
This is a cognizable offence and the following is the procedure followed in cases under Section 498A:
1. Complaint is lodged in Police Station which is then transferred to Mahila Thana or the Crime Against Women cell.
2. The CAW cell attempts reconciliation or settlement.
3. If mediation by CAW cell is not effective then an FIR is registered.
4. Arrest is made by the Police.The accused can file for Bail/ Anticipatory Bail/ Stay on Arrest.
5. Police conducts investigation and submits charge sheet to the court. Further, the Court frames the charges.
6. The prosecution and defence produces evidence.
7. The Magistrate examines the accused, which is followed by arguments presented from both sides.
8. Based on the above process, the court passes an order or judgement that it deems fit.
Now to answer your specific question, no the Police does not compulsorily need to inform your employer about the complaint received as it is not expressly mentioned anywhere as a protocol. However, under different circumstances the event may be unavoidable, for instance if an arrest has to be made at the workplace.
In case the Police has informed your employer then the termination will depend on your employment contract. If your contract states that your involvement in legal proceedings may amount to termination, then the employer is in a position to do the same.
Hope this helps.
