Seriously?
Teachers get a LOT of holiday - that is one of the perks of the job (and what keeps us going when we're still marking books at 10pm

) but the
compromise is that you don't get to choose your holiday. We work 195 days a year compared to the average 230 - that's
thirteen weeks holiday (kids get 14!

) so I'm not about to complain if I have to pay a bit extra to go during the school holidays (and my partner - who chose
not to work in education - also has to pay extra, despite being able to jet off whenever he feels like it).
I can't even imagine suggesting to my school that they let us take time off during the term time

If we are not there, who teaches the students? Illness is one thing - it's unavoidable - but supply teachers are
expensive (and rightly so - they are professionals just like us). The (hypothetical) bill I'd get from the school to cover my absence would FAR outweigh any benefits I'd get by jetting off to Orlando in term time

Plus, I do genuinely care about my students' progress and continuity of teaching counts a lot toward that - and I'm sure parents would be simply delighted if their child's teacher went off to WDW in early May to save a few quid - just weeks before their child's GCSE/A Level exams...
I'm happy to set and mark work for absentees for two reasons: firstly, I care about them making good progress, being happy and enjoying their learning; secondly, if I
don't set work, they've missed content. Since I don't teach anything the students don't
need to know to progress forward in their education, they have to cover the content: so either I set and mark the work whilst they're on holiday or I have to spend time one-to-one with that child later on going over the work they missed. It's also much easier to explain what we did in one lesson if a student is unwell (rarely are children absent from school for more than 2-3 days in my experience), as we recap the previous lesson at the beginning of the next, than it is to explain weeks of content - all of which is cumulative skills/understanding/knowledge - if a student goes off on holiday. So whilst I don't get upset, offended etc. if my students are absent for holidays (as it's nothing to do with me - that's for the headteacher or the LEA to decide), I
do try to plan, set & mark work whilst they're away because
it is in their interest. I want them to succeed and as a teacher I believe I should do the best I can to help any child achieve their best.
I am childless so I have simply an educational standpoint - the policy setting is not my jurisdiction so I believe that both schools, LEAs and parents must do what they feel is best for the children in their care. If they believe not allowing holiday is the best thing to do for their children, I don't believe they take that decision lightly.
