Let me start off by saying that I always thought I'd like to do jury service one day.
Now I've discovered that not only do my employers not pay you when you're on jury service, the rates courts pay you for loss of earnings are paltry - the sum I'd get for the first 10 days would be less than half what I'd actually lose, and rates from day 11 are still less than my wages so I couldn't actually afford to do it www.gov.uk/jury-service/what-you-can-claim
Can you refuse to do jury service on the grounds that you can't afford the loss of earnings? I'm single and have rent to pay, for context.
