Yes
Work related issues are to be relayed through internal email and the weekly meeting minutes. We even have group chat on work cell phones.
In emergencies, I can be contacted on my cell phone.
The group chat on the personal cell phones can kiss my ass
So they have it on work cell phones? do you have a work cell phone and personal or just personal?
I think too many people are putting too much emphases and resilience on texting when calling is probably the better solution if it's important. If it's not, e-mail it.
I wouldn't do it simply because it involves installing whatsapp or however it's spelled. screw that garbage software. And as DigDog said, it isn't secure either. Granted, i'm not sure e-mail through exchange sync is either. It isn't like the old blackberry server.
I'm on call 24/7 now and i keep my e-mail and text alerts silent. Everyone has my on call number and personal cell number to reach me if it's important. (on call number forwards to my personal cell. no company phone for me) the problem i have with this is some people like calling for important issues and not leaving a message.... But the reason i have my alerts set to silent is we get too many junk messages through e-mail and txt. many come late at night when i'm trying to sleep. I'd bet that group chat thing will do something similar if who ever is in charge of the group doesn't squash it as soon as it starts. but chances are, it will be that person that starts it.
