“‘Chav’ is a mainly derogatory slang term in the United Kingdom for a person whose lifestyle, branded casual clothing (especially if counterfeit), speech and/or mannerisms are perceived to be common, proletarian and vulgar. ‘Chav’ is often used as a stereotype to refer to white, poorly educated, aggressive youths, but youth and aggression are not the defining attributes of a ‘chav’. The term is similar to America’s ‘white trash’ stereotype.”

I don’t know that I have a fully formulated thought as to whether the firings were appropriate or not. I’m a bit torn. Still, I’m always glad to help with the linguistics.
