Thursdays at work are busy days. As such, my WorkPace breaks sometimes get missed. I realize that they are there for a reason, reducing my RSI pain, but sometimes I just need to get something done. If you ignore any breaks, then your notification icon buddy gets progressively more angry. This face is what you get with a 43% compliance. I have only gone as low as 27%, so I'm not sure what would happen if you ignore him completely all day. The number beside him (5) indicates my work level. I think it measures some combination of my keystrokes and mouse usage to determine that... somehow.
I did get to see the face at 17% compliance, pretty pissed off I would say.
