Poor

One year after we moved into our new offices now and the complaining will not stop. Something new every other day...

Today they installed this little device in my office - it measures the CO2-content of the air. As you can see - it says "poor".
It says "good" if it measures around 400 ppm, normal up to 1000 ppm. Good lasts for about 5 minutes after I close the windows. And today I had the office all to myself!
No idea what will happen next after they read out the recorded data on this piece.  Until then - its "freeze" or "choke".
