I work at a high volume and have Starbucks and cafe and am struggling with that alone. I can't imagine having all three. Work your ten days, say goodbye, and good luck in your new adventure!
i don't think you'd get fired over one NCNS in the last year but you really should have asked for the LOD. You've worked there for 4 years so you should know that you need to speak to the LOD to call out. Next time you call out ask to be transferred to the LOD so you can talk to them.
