Some of the views on these threads are so boring now. People are clearly unwilling to change their entrenched views.
Just because some state schools aren't doing much, and two private schools have been reported as opening, then why must that mean the hardworking teachers should be punished accordingly by working through their how many times must this be explained unpaid holiday.
If people have a problem with what is being set, contact the individual school.
Finally, working from July-December with only a couple of weeks' break (presumably that is what is being suggested) will be pretty educationally invaluable: kids are dragging themselves through by mid-November at the best of times and learning/behaviour significantly deteriorates in the last two or three weeks of term because they're tired, overworked and ready for a holiday. Far better to let them enjoy their freedom, get out into the fresh air and see their friends over the holidays, than make them come into school to meet some arbitrarily decided educational point by a certain time of the year.
You can be rest assured that teachers will work their hardest to plug any "gaps" come September.
