Jury time is paid time off at my US company. And at least at the US Federal level there's a daily stipend for sitting on one. Lower level courts may vary on that.
Many people in the US do not work for your company.
Federal juror pay is $50 daily.[1] This would be 8 hours or less of minimum wage.[2] States pay from $0 to $50 seemingly.[3]
8 states and 1 district had any employer jury pay law. All other than Nebraska excluded small employers, excluded part time employees, allowed to pay under minimum wage, allowed to pay nothing after 5 days or less, or allowed to force employees to use paid time off.[4]
Juries are unpaid and obscure. I think most people in the UK would be delighted to sit in Parliament for the a £100k an year salary + expenses (what MP's currently get) plus a lot of prestige and the experience. It would be a pretty good thing to have on your CV!
Jury service in the UK is generally seen in a positive light ( despite having far too much hanging around ).
I suspect the US problems could be easily fixed by forcing employers to pay you while you are doing it.
