I Need Help on Farting Poop?

I have large farts all the time. Large pieces of my own feces squirt out. Sometimes they are very watery and other time hard as a rock. It is very embarring especially when I am working. I have to take 5 pairs of underwear with me and take many trips to the washroom to wipe the **** out. I hide my underwear under the sink and there are many pairs there. It is starting to become very, very, very, smelly and many workers are becoming concerned. On Monday they are going to clean the whole work place. What do I do if they find my underwear?
