Katek, in regard to your post @17:16 today, I do not believe that anyone has suggested in this thread that teachers should work twelve hours per day five days per week.
However, how do you think that your supermarket and pharmacy shelves have remained stocked if it were not for truck drivers and distribution centre operatives working upto fifteen or sixteen hours per day, six days per week under the emergency legislation for transport throughout this crisis?
You demonstrate by your comments Katek that the teaching profession do not wish to in any way countenance changed methods of working or extend their working day for the benefit of the children they teach or this nation in this present unprecedented crisis.
Indeed, extended hours of working may not be necessary in schools if by example all history lessons were taken in the 08:00am until 02:00pm school shift session. In that, a class of thirty could receive a lesson by way of two groups of fifteen in different classrooms one with the teacher live in one while the other could be live online in the next classroom.
English lessons could then be conducted by way of the same method in the 02:00pm until 08:00pm school shift session.
The above is only put forward as a suggestion towards fresh thinking in the teaching profession to accommodate the present crisis, for it may well be that the Covid-19 situation may be no different in September than is the situation at the present time.
Just what would you suggest then Katek, that the schools remain closed indefinitely??
