My only experience is with the call center. So my feedback is limited to that.
Heavy call volume with the short breaks is hard. On slammed days I felt as though I had to choose on out of my two twenty minute breaks which one was to scarf food down and which would allow me to use a restroom. I also thing the environment needs to be fixed. Big call centers need to be able to be ready for the noise. It's a beautiful center but I could never get my volume high enough on any console or headset to hear the callers clearly and the callers often could hear the loud background noise and it was frustrating on both sides.
