4 years ago dh was refused leave to go to his uncle's funeral - his uncle was like a 2nd dad to him. he took holiday leave and they "overlooked" the fact he hadn't given the standard 7 days notice .
Tomorrow he's been allowed leave to go to his Cousin's funeral (who to be honest he hardly knew, but his dad is a bit of a mess about him dying before his sister - so it will be helpful), on Christmas eve with half the staff already missing.
The list of relations for bereavement leave is in his contract, but it seems there are no rules for just popping out to a funeral in the middle of the day.
