Mine varies. This week - none at all - I'm home recovering
Out of term time - mostly I can work at home if I wish - I'm contactable by phone and email, as long as I go in once or so a week.
During term time, it depends on the teaching day. If I'm doing evening teaching it can be 10 am - 9 pm but the rest of the time it's pretty standard. Although when I'm busy, I'm really busy - I can be marking all weekend and til 11 pm.
