It's bailiff.
Here, if you have jury duty, you call in the night before and see if your number is called to come in the next day. The last time I had jury duty, I ended up not having to go in at all, but was told when I e-mailed and asked that I had fulfilled my duty and would not be called again anytime soon.
But, once long ago, we were all made to wait in an uncomfortable basement. And that included a teacher who said they had come and dragged him out of his classroom!
