I'm concerned that because I was offered and accepted a job 4 weeks ago and haven't signed my contract yet, that it will be offered to someone else. I'm supposed to start on Monday the 12th as an aide for summer school and then I'll be teaching in the fall. I'm just really excited about this job but nervous that something may go wrong. I guess my question is, is it possible that an employer can offer a job to someone else if I have already accepted the position? Sorry if this is super silly, but like I said I'm just sitting around worrying.
