People are aware that social workers need to be non-judgemental, right?
Social work is a difficult career, some 18-year-olds are prepared for that, some 40-year-olds aren't, there are a lot of factors involved. When I was training there was more than one student over 40, who had worked in social care their entire lives, who were very unprofessional/judgemental/uninterested/unempathic, and younger students that were the complete opposite.
Working with social workers isn't the same as being a social worker, so maybe everyone should wait until they have actually experienced social work itself, as a student or a qualified social worker, before judging others.
