I do work for an organisation as do lots of other individuals. We are not colleagues as such and do not know each other or need to contact each other, but the organisation does and they usually do this by email or text.
Today, they set up a WhatsApp group without asking and with all of us as members. I now have all their numbers and they mine and none of us was asked.
Is this okay? I don't know any of these people in real life. I wasn't pleased.
