right this has been a massive shock for me, we found my grandad passed away in his shed last night

which i am devistated by. the doctors think it was a massive heart attack- but we have to await the post mortem to find out what happened.
question is, i have a week off this week on ANNUAL LEAVE, do you know if i could have this changed to compassionate leave and have my annual leave given back to me as its hardly time now to enjoy annual leave.
many thanks people
