I was hired as a casual employee at the long daycare I did my work placement at while I was a student. I really liked the centre and despite being casual I was working 3-5 full days a week. However, since the new year I have been getting just a few shifts a month, mostly lunch covers, almost all of them being called in the night before or the morning of. The commute is long too so I ultimately decided I needed to work somewhere closer to home.
I found a job down the road from my house, checked my roster to see I had no shifts for april or may, so I resigned over email. In my email I immensely thanked my boss for all her support the past 18 months and asked for her reference and if I need to return my uniform, as I have done in the past when resigning over email.
I did not get a reply or phone call but I was removed from the system/work app. It has now been 10 days and still no reply. I can't bring myself to send a follow up email because I know they have seen it. I feel like I have broken an unspoken rule or done something wrong.
Is this considered rude, unprofessional, or just not what is done in this industry? In the industry I used to work in, it was standard practice to resign over email and would be inefficient to go all the way in to work just to resign without a paper trail.
I'm also more worried about this because I really need her reference and my uniform is still sitting in my drawer.
