DS is now Year 8. In Year 8 the dcs help out the reception desk. DS has done this twice this term already. it's not just one period. it is for 3 periods at a time. Today he will miss the lesson before lunch and all afternoon.
I have no problem with the idea and of course DS thinks it's great fun, love the responsibility etc and gets to carry a walkie talkie
Just think twice in a half term is a bit much.
Any other schools do this
