My DH has a hobby (motorcross) that means he often spends entire weekends in the summer doing the hobby around the country (for 8 weekends). We join him on some weekends, but just watch. The kids and I do not share his interest in it but we go to support him. In principle I agree with him doing this hobby because before it he did nothing so it has been good for him. However, each weekend he has to go to a different circuit and he always takes the friday off to go and test the bikes and practise. So, that's 8 holiday days on his hobby. Two further races are week day races so that is a further 6 days off work (3 days for each race). So he spends 14 days of his 25 days annual leave allocation on his hobby.
Add to the fact the boys skiing holiday in January which was another 3 days off work. So, this year he will have taken 17 days of his annual leave off doing something just for him, and as a result says that he can't come to school events during the day because he can't take any more time off.
This is taking the piss isn't it?
