DH works in a male orientated environment and recently someone was outed as cross dressing in secret. The person who outed them announced it to three different shifts and made a big deal of it. DH felt awkward and didn't enter any discussion about it.
Today he got an invite to a WhatsApp group from the person who outed them telling everyone not to mention it and to delete the message as the situation had escalated. He immediately removed himself from the what's app group but is a worried a) about this persons MH and b) that he will be implicated in the situation. He is good mates with the person and is really concerned. He can't go to his union rep as they are close friends with the person who is spreading this info.
Is there anything he should do to ensure he isn't sucked into the situation.
