So I just started subbing at a high school, this is the school where I want to end up working after I finish my Masters, so I want to make a good impression. So far I've been subbing almost every day, I've only rejected a job with AESOP a couple times, and always try to mark days as a "non-work day" in advance. But since this is my first "real job", I have some questions about etiquette. In December, I plan to go out of town for about a month. Mind you, the school does have winter break, but they only have 2 weeks of it and I plan on leaving 4 or 5 weeks. So, is a substitute like a regular job where they give me certain vacation days? Would I lose the job if I go away for so long? Do I email someone about it, or just mark it as "non work days" on the AESOP calendar? Any advice I can get would be much appreciated. Thanks!
