I have been a CM for 2.5 years now. I find it very hard to have time off.
My busiest times are during the school holidays obviously, so I dont like taking time off then as I feel I am letting the parents down, yet I am unable to take my children out of school in term time for holidays.
So, for the last two years I have just taken 2 weeks off at the beginning of the summer Hols and the couple of days between xmas and new year.
This works out at about 2.5 weeks a year.
What do other CM's do about taking holidays and how much time do you take off?
