Thats fucking bollocks mate, I'm all for people using saying racism when there is actual racism going on, but that just takes the fucking PISS. talk to your manager(s), show them the work you do, compare to the fuck ups said guy has done, and tell them who'll bring in the most money or is worth paying. That's got me riled up now. Can you not change shift or something, and get to carry on doing the thing you;re damn good at?
