Nope, not sulking. Not about this anyway,
I talked to the other work-from-homer in my company and while he is by no means veg*n, he was very empathetic with regards to the pressure they tried to put on me to go. He doesn't want to go either, because like for me, it is not particularly convenient for him.
What I *may* do is show up for dessert. It's something one of them suggested, and I was non-committal, but it may be what I'll do. It's a pain in the ass to drive out there, but it would be a solution where I don't have to be around the consumption of huge amounts of cow carcass, but can still put in my time and not look like a bad sport.
I don't know that my co-workers even have a "problem" with me per se, but they sure don't understand that when I'm already working 15 hour days, I'm not going to be thrilled when they want me to pick up their slack. A friend I have who works there has heard things, that certain people are annoyed with me for "complaining" too much-- well, sooooorry if I'm not interested in working more than 75 hours a week while said annoyed person puts in 25-30, to do something that they should have taken care of.
Anyway... the good news is my boss told me yesterday that he sees I am way too stressed out and doing way more work than anyone else and he has decided to give me a bigger budget to farm out more of the work to freelancers. So that's a good thing for now.
Thanks to everyone for their input.
This is my first job out of University and I'm still "learning the ropes."
