They want me to stay on right now because it's very hard to fill the job. The hours are awful. I reckon it's going to take them a good 2-3 months to fill it, maybe even longer because people will start, realize how awful the hours actually are, and then quit pretty soon.

On top of that, it's really only a two person job. One person works 4 days, the other works 3. I work the latter. So in theory, if they did stay true to their word, it would actually be more of a hassle for them to keep me once they did find another person who would stick with it. Especially because the current 4-day person refuses to switch shifts or cover even in emergencies, so my managers will likely have to cover my vacation (albeit only a day or two since I'll only be working those two days), if they find someone who can only work two days (which I feel is unlikely in itself)

sorry if this is confusing or coming off as paranoia (which it probably is lol). I just keep getting the feeling they're saying what they need to say in order for me to stay on until they find a permanent replacement, and then they're probably not going to find it worth it to keep me in the end. Which from a company standpoint I get, but from my personal standpoint, massively defeats the purpose :P
