One of my co-workers is a total slob. Her desk is next to mine. I can ignore (barely) the pile of papers and general filing chaos that is in full view on the desktop. The problem is the food wrappers that she stashes in her drawers, sometimes complete with some tidbits of leftover food. I swear I can smell it but my boss said he did not notice any off odors. (He checked after I talked to him about the mess.). My boss said he talked to my co-worker about cleaning up her act, but I have not noticed any improvement. How can I convince him to do something? Should I point out that the trash is going to attract vermin?
