I've been in my current position for a couple of months now- roughly since the start of November. Although I'm pretty stoked to have a permanent position after a long time temping, I'm starting to feel that this job may not be a great match for me.
Without going into a lot of details, I'm not doing as much of Task A, which is what I was hired for, and more of Task B, which I am adequate but not great at. This is causing some frustration both for me and my boss. Also, although the hours are normal on paper, in practice I'm spending an extra half hour to an hour at work every day. This and other issues have led me to the conclusion that I will probably be happier if I start looking for a new position. They're all warm, well-meaning people, but it's just not a good fit.
My question is, do you think a potential employer would feel iffy about hiring someone who's leaving a position they've only had for a couple of months? Is there a minimum length of time that I should stay before I start looking around?
Also, I'm not sure what to say if potential employers ask why I'm looking for a new position. My reasons seem like good, solid reasons to me. But I'm afraid that to someone looking to hire it might make me look like a flight risk who'll jump ship at the first sign of a better job. How do I convey to them that I'd be glad to stay at one place for a very long time if I could do the job I was hired to do at the times I was hired to do it?
