I'm working class as f - raised to communicate with a strong regional accent, using regional slang, combined of course with at least one or two profanities per sentence. I view the phase, "what's up, dickhead?" as friendly way to greet a friend. I don't know anyone in my family who works a middle class job. You're either unemployed or postman around here. Growing up my school was so bad you were lucky to leave with a few GCSEs. In general you were far more likely to leave with a kid or a smoking addiction. My whole adult life has been a learning experience. I remember first being confused when people mocked how I spoke in university. It wasn't just one or two people either, literally everyone I spoke with would comment on how I spoke. In terms of work, I'm not sure how it's impacted my ability to find work, but I don't think it's helped. Several years ago when I was still learning how to not be working class I had an interview in which I was asked a question I knew I knew the answer to, but just couldn't quite recall. I said something like, "fuck, I know this but can't remember". I didn't swear consciously, it's just automatic, but the interviewer lost it and terminated the interview on the spot saying I was wasting his time. That really upset me as I was having a hard enough time finding work as it was. At one point in my career I ended up working for a start-up incubator in London which was interesting. Everyone there was unbelievably well spoken and while at that point I was starting to get good at not coming across as working class I did get comments whenever we'd go out drinking because I'd temporarily find it difficult to speak proper. Not nasty comments or anything though - they were all really nice - but people obviously noticed and were confused why someone in real life was talking like they were on Jeremy Kyle. I think the hardest part of it is having to self-censor my sense of humour because what I deem offensive or unacceptable is completely out of whack with those I work with. My humour seems to be quite mean which I think is normal for working class people. Like I can joke about literally anything with school friends, but I have to be very careful with jokes at work. Calling someone a gayboy as a joke for doing something a bit gay is unacceptable for example. I also don't seem to know when people are being mean. Middle class people tend to be very easily offended and will hold in their feelings so it's hard to know if you're offending them. I'm not used to that. Growing up people would speak very plainly with each other so that's by far the hardest part for me. I think I'm quite an extreme example of this class divide though. I'm also not sure what the answer is. I judge people who speak like myself force more harshly than anyone I work with. Unlike people I work with I know people from my background are generally trashy.
