A few depts where I work have all moved into the same office. This was previously vacant.
There is no fresh air flow, no windows you can open or doors just an air conditioning system.
For weeks my eyes would dry out and get burny in the early afternoon and now about 6 of us have all got various eye issues (out of an office of about 20). Turns out we all has that dry burny feeling...
About another 6 or 7 have got hacking coughs.
I had two days off this week and my eyes were almost better. Went back to work yesterday and back to runny itchy burny gunky eyes last night.
