I've been a stay at home mommy for 10 years or so. My problem with jury duty is child care. When the kids were younger, before they started school, as long as they were potty trained, I was told that I could bring them to the court's daycare. Yet every time I was called, it was to a court that did not have day care. Go figure. Now that they are all in school, I need to be able to leave to pick them up from school. So I am no good between 1:45-3:00. Unfortunately, they aren't very sympathetic about that topic. I usually have to have my mom come and stay at my house so that she can pick them up. Which isn't really convenient for her.
The last time I had jury duty I sat next to a teacher and she had a very interesting proposal: they should take their jury pools out of those on disability, unemployment, or welfare. There was also a man there in tears because he was a small business owner and missing a day of work meant missing out on a day of pay. He did not get excused.
