Harassment Against Female Employees On WhatsApp

1. This clearly falls under sexual harassment. If there is an Internal complaints committee under the sexual harassment at workplace act, then you can complaint there. You can find the procedure here. If not, you can alternatively seek help of police by lodging a FIR.
2. In case of sexual harassment, the position/ status of the alleged offender and victim does not matter (legally speaking)

Dear SecureplusSolutions,
Thankyou for noting the changing sensitivities at work and the policies that will be impacted by them. Even a Water-Cooler moment can easily run out of the hands if the boundaries are not set. We cannot leave every delivery to common sense, as what one may deduce as something can mean entirely different to others.
You are right about pointing it out to your friend. However, your friend may need more handholding than you realise.
Here's a thread where we have been discussing policies for WhatsApp. It could be a pointer for your friend.

Hi Kavita,
If I would have been in your place than I will put a message soon after his message "Please maintain the decorum of the group, please post official matters only", if the person continued than should Remove him from the group and if that is also not possible than remove all the people from the group and DELETE the group.
This will a great lesson for that person and you will set example to others also that this is not acceptable.
Regards
Neha
