I need whatsapp to communicate with global KOLs for work.

Shouldn't they be required to offer a work phone if they require you to install an app on a phone? It may depend on where you live

My company provides us with a $100 a month cell phone stipend instead of giving us phones.

If you're running android I believe you can set up a work profile with its own apps. On graphene you definitely can, with its own filesystem and everything.

I wouldn't install work programs directly on my devices without some kind of sandboxing because of cases like this.
