Several coworkers and I share a rather small working area (not absurdly tiny, but small enough to cause this problem). Most of us usually eat lunch in the cafeteria area, and sometimes at our desks. One coworker, though, always eats lunch at her desk. I'm not sure what exactly it is that she is eating, but it has a rather strong (and unpleasant) smell to it, which some of us find nauseating/distracting. It often lingers in our workspace until mid-afternoon.
What can we do about this? Our coworker obviously has the right to eat whatever she chooses for her lunch, but it's causing an unpleasant work environment for the rest of us. We should be comfortable in our own environment to be able to do our job, but we can't really force her to change her daily lunch to accommodate that, can we?
