Would this have to be advertised?

Permanent pt teacher leaving.

Another pt teacher on a temporary contract - could they just have their hours increased to match the freed up post, or would it need to be advertised?

I don't think it does have to be advertised. If they do advertise it could be internally(for part timer to increase hours) or someone else to drop down-unlikely!

I think it should be advertised hopefully internally
Because someone else in the school might want the opportunity
