I'm kinda freaking out...

I told my boss that I needed off for 2 weeks for surgery. I had told him about 3 weeks ago that it was coming so it wasn't a total shock. He didn't seem bothered. I thought that I'd feel a sense of relief but I have MORE anxiety now than before. He is in with the owners, I feel like they are discussing it. I'm afraid that they aren't going to pay me although I have about 6 days so I would get some pay. I'm just plain concerned because I've seen how they've handled letting these people go over the past week. They aren't necessarily the most compassionate people in the world... Hopefully, it just won't be an issue!
