My coworker is sick... should I work from home?

The woman who sits next to me at work is complaining to anyone who will listen that she feels horribly sick. The last guy she said it to even sarcastically said “so, youre here, share it with us all then!” and she just LAUGHED.

Let me also say, I have severe OCD and germs phobia. I seriously cannot focus on my work right now because I’m so stressed about catching this woman’s cold.

My boss and everyone on my team at work all work in different offices. I am the only person on my team who works in my office. He lets us take the occasional work from home day if we need. Honestly if I left, I’d be more productive because I wouldn’t be anxious about this sick woman, and no one would probably even know otherwise.

I also don’t want to take advantage of the work from home... and I’d rather save it for when I’m not feeling well. But if I stay, then I really might get sick and THEN I’ll stay home because I’m not selfish. I’m just fumingly angry that I’m put in this position! Why should I either have to (1) be stressed and risk getting sick (2) go home ?? SHE should go home!

Is it better to leave today preemptively? What about tomorrow? What about the next time she’s sick......? Cold and flu season is only just beginning and I feel like I can’t breathe from the anxiety 😖
