Keep being called posh at work

[Consciousuncouplings]

I've lived on and off in Manchester for a lot of my life but spent around 10 years of my childhood 20 miles away. I've been back in Manchester now for around 5 years, I don't really have the accent, it's quite a neutral one and it's hard to pinpoint exactly where from I think.
I work for a place in Manchester where a lot of the colleagues are from around that area or live close by, most have quite a broad accent.

I've been referred to as posh by them a few times, one the other day commented on 'my accent.'

I once said something and one said 'Oh I thought you'd be too posh to say that."

They're acting as though I speak like the Royal Family, far from it! I'm not posh in the slightest, and my accent is just very neutral, I spent some childhood in a market town about 20 miles away like I say.

I don't know why it bothers me really, but some people seem to associate you with thinking you're above others, snobby and so on and I'm none of those.
When they say it I just say 'no I'm not.'
Does anyone else get things like this and how do you deal with it?

I had similar when living in Scotland. I was told I sound very home counties. I am from the East end of London 😅

It’s so sad and says more about you than them. I had this when I was at university up north and brought up down south. Was presumed to be posh and rich and snooty when my parents earnt half what the northerner who was goading me’s parents earnt. I ended up pitying them for sadly being full of shit. I wouldn’t do that to someone else cos I’d think it was dicky. And i don’t have any respect for people who behave like dicks.
I’d be tempted to say “really? I can be a lot posher than that, I tone it down for you lot hahahaha” and at some point “sigh & say they sound like a broken record, and does this pass for good conversation round here, hahaha”

Then than you even!

I'm told my accent is RP but I'm not bothered whar others think about it. As long as you can make yourself understood what does it matter?

My mum is from the Black Country and I love the accent; it is partly nostalgia, I know (it takes me back to childhood family visits) but I do think it's beautiful.
