Re: November 4th: USA
I've served once for a local grand jury duty... and a second time called for petit jury duty and taken to a different part of the state to serve for a little less than a week. In the end... it turned out myself and another were only alternates, so we did not actually cast a vote in the end. However, we were only told at the very end. [presumably so if someone had to 'bow' out, that there could be no cries that we had not paid attention]
Otherwise, I believe I have been called a few times to be available a few other times. However, I think only one of those others was I asked to come to the courthouse, and even then, I wasn't even asked to answer anything other than my survey, and simply was allowed to go home after a few hours.
I didn't particularly look forward to the process, but did feel that if I was chosen, I should make myself available. I was amused by some people's reasons for not being available. Some seemed legitimate. Others seemed less so. Several people said their jobs couldn't live without them, and they would have to contact them. Interesting enough, I don't know anyone who's employer said no.
I found that service interesting timing as it was not far off time-wise from the time I was called to be a witness in a different case. It was a time where I saw the process from a couple different perspectives.
I have to admit, luckily neither were a financial hardship for me to have been able to 'serve'. I can understand why someone barely making it would find serving even harder, as you certainly don't get much.
