I work in a supermarket where a new ops manager has been appointed. I found out recently that there is a group chat for the managers where they have been commenting on the staff that work in the area of the store where I work. The terms that have been used to describe us who work in this department by certain members of management can only be described as disgusting and derogatory and I am willing to take this further. However, AIBU to ask to see these messages or will the fact that another manager having described what has been said be enough for me to take it to either our union or HR?
