I have interviewed for two positions this week: one was for a high school social studies position (yesterday) and the other was a permanent substitute position at a local middle school (today). The permanent sub position called and offered me the job, so I accepted. Here is my dilemma: the high school position is still interviewing today and there may/may not be second interviews (depending on how the principal feels about how the interviews went). This was the position I really, really want. Hypothetically speaking, if the high school interviewed panned out, would it be unethical to back out of offer 1 (the permanent subbing position)? I am really worried about losing my health insurance in November and the permanent sub position does not have benefits. However, I would feel bad about backing out. I have been on so many interviews and had five rejections before this, so the prospect of having nothing next year was very scary. Of course, the question could always be null anyways if the high school doesn't call back. I just feel very new to all of this. Any help would be appreciated.
