Is it okay to call?

I would say no.

I can only speak from the way things are at the places I've worked. When I worked hospitals, there was usually a separate HR dept and from what I have gleaned is that it's ok to call..... ONCE... and I wouldn't necessarily call to "check on the status"... simply call to ask if the position is still open. If it is, then you know that it's possible that the apps are still under review or haven't been gotten to yet. If it's closed, then that's all you need to know. Where I work now.... we have no HR department, we have a few of us who have been there long enough and are trusted enough to go through apps and do interviews. Sometimes it takes us a while to be able to get together and go over things and share notes. We realize that it can be nerve wracking to the people who applied but we do the best we can. I'd give it some time, at least a week or so and then, like I said, ask about the position and not your individual application. Just my opinion.

That's how I got my job. After months of applying everywhere I called and they scheduled me an interview right then and I got the job :-)

If it has been a week or 10 days, I would call the HR department and follow up on the status of your application, and if they are scheduling interviews at this time. If the position has already been filled, then you can at least know were the hiring process is at. If the position has been filled, ask if there's any per diem positions available (if that is something you are interested in). Lastly, I would ask that if you see another position available for them in the future, can you re-activate your application (do they keep them on file) or do they prefer a new application? In my experience, in this job market, you really have to advocate for yourself.

Thanks for the advice everyone :) It was tough like this too when I became a CNA in 2009. After I got my first job though and about a year of experience, when I filled out an application, the facility would call me back. But since I'm a newbie again, time to work the phones! Lol.
