I have handed in my notice last week (approx 2 weeks before the cut off date) as i am moving to a school nearby where i live. I am an NQT and this is my first time dealing with resignation in a school. I emailed the notice to my headteacher and another member of the SLT. I then went and let that member of SLT know that i emailed my notice in and copied them in too. My HOD was present when i emailed the notice. However i am yet to still receive an email of acknowledgement from the head. I am aware that the SLT and my HOD have already started looking for candidates for the job. My question is should i be concerned that i have not received a reply of acknowledgement from the head? I have seen the head around and we have said our usual hello's and hi's since I've emailed him but he has not said anything about it. Should i be concerned? I have accepted my other job offer already.
