You've got to personally talk to whoever is doing the hiring. Either call them or visit their location to say, "Hey, I've applied online and would love to be considered!" It shows that you have a little more initiative than many others and that you actually know who and where you are applying to work for.
I understand your plight, though. I have been looking for reliable and ethical work for 2½ years now, finding only seasonal work (which I love but isn't enough) and cult-like sales jobs (which I left due to ethical differences).
