Since being veggie, I've worked at only one place that I had issues with. In my second or third year of being veggie, I workd at a Dunkin Donuts for two years. It was a horrid job, but I was young and stupid, hehe. When I worked nights (it was a 24 hour 'restaurant'), I'd have to make countless crossiant/english muffin sandwiches which came in three varieties: bacon, sausage, or ham.
I never liked doing it. It bothered me, but I knew I couldn't just say I don't want to. Well, that was my first and last job in the food industry, as I've since moved on to printing and media.
I do sometimes have to print things that bother me at my day job. Once, we were printing an Agway (agricultural company) employee magazine. I had to scan a photo of one of those cows with a window (they surgically make it possible to reach in to the animal for studies). I was highly against it, but again, we are all slaves to the dollar.
My company I run after I leave my day job is for producing various media. I ideally would love to never take on any clients that sell meat based foods. I already lost though, as a friend of mine needed a website for his Chinese restaurant. Oh well.
I think it comes do to just grinning and bearing it sometimes. I certainly could not work anywhere that sells meat anymore, though. I've adopted a bit of Hare Krishna philosophy about not serving meat to anyone.
