From my experience, if you have a prebooked appointment you tell them on the first day and they do their best to accommodate, one chap in ours was due to go to the grand national and allowed the day off for it (the Friday of the racing). It's also unlikely to last more than 2 weeks and you'll get referred to as first week or second week jurors. If a case does look like it could last longer you can inform the judge who might swap you out of a jury, if it lasts longer and you're on it I think it's pretty well tough luck though.Ahh bugger, just received the letter.
The thing says I got to start on Monday 10th June, and usually last 10 working days, that is fine. But it says that it can continue for more than 10 working days.
On the 30th June I have a big event on I cannot miss, this will be the 15th working day, is there anyway you can get out of one day or phone in sick?
Otherwise do you think its best to fill the form in providing a later date and not risk it?
