Had a quick look. Nothing saying whether could choose sex of social worker.
Can ask for different one but rare to get change.
Meaning unless I missed something-
SW mainly female some male
Request sex looks like not a thing
And they're not doing anything intimate etc are they.
What surely most important is they good at their job. Empathy, real help etc when needed, concern followed up and acted on if needed.
To be kind but look out for things. Not get wool pulled over eyes by charming liars. Not make snap judgements, decide understand what's going on due to bias etc.
OP you say would be upset male SW. What are your reasons?
As you say pretty much can always tell male. So you've got a male social worker. So what.
If can't tell vvv unusual then what harm are you actually caused in this context?
As long as they good at job etc then imo so what? Ok if find out then wtf but if you happy with their approach, attitude, advice etc then in the end is it really s big deal? Better than a horrible one of either sex surely.
Plus of course.
PPs have checked and register etc mean pretty certain indeed this person not SW anyway.
Your current SW you sure not trans.
Likelihood of getting a TW (or TM?) SW got to be tiny.
I think you're worrying over nothing here tbh.
I assume you live in Bolton that's how saw article. Local. This person not SW 99.999% certainty so you're not going to get as SW.
And if you did know male so as per previous comments. As long as decent at job then ok maybe not 100% keen based on what know from article but surely not enough of concern to get so worried about?
