In my county you have to call in each day for a week.
I’m a believer in doing my civic duty, but that just seems completely unreasonable!
The alternative, which we used to use, was showing up every day for a week. We had everyone appear and then sorted them, and those not picked in the first day kept showing up every day for the week (or until there were no more trials scheduled). They went to the call-in system and then you might only have had to show up on a Wednesday and not have spent the last 2 days reading the newspaper in a big room.
We did mental health commitments hearing/trials on Fridays at 3 pm. We had one person who requested a jury trial. If we hadn’t gone to a call in system, those jurors would have been sitting around all week waiting for Friday at 3 pm. And not only those 6 who were picked because we needed a pool of jurors, so probably 30 people sitting around all week.
