Auschwitz?

So maybe I'm being a little extreme in thinking my workplace is becoming like a Nazi concentration camp, but today was a little extreme.

I work in a pretty relaxed atmosphere. We are in a room that has restricted access due to the things we package. So, it's just pretty much our team, and occassionally outsiders come in for various reasons. Well my one co-worker got pulled aside today and our group leader talked to her. She was told that while our group leader likes how happy and cheerful she is, not everyone does. So, she needs to tone down her happy and boisterous ways. Huh? What? We can't laugh anymore? We can't smile? We can't have fun?

What's the point of going to work then? The work sucks and the only redeeming quality of the place is that we make it fun.
