next time my job asks me to install teams on my phone, I'm gonna hand them a list of rental costs for access to my phone/internet and to cover any security related issues.
I actually like the flexibility, but Teams is installed in a work profile that I created. This way I can turn it off when the work day is over. Very useful!
You know you can have that flexibility with a work phone, right? Without them monitoring, and controlling your device?

How are they monitoring and controlling my device when they don’t have MDM access to it? Again, I created the work profile myself. All my company IT could have access to are the Microsoft apps I’ve installed in the work profile which is separated & turned off when I don’t need it.

If I have a second phone, I need to keep it charged, remember to take it with me, and to turn it off after work. With everything integrated into my private phone it’s much easier for me.
