It's been awhile since I got called for anything in that area but Springfield is an tech desert. The only company near there is Marathon and those people aren't living in Springfield either.
Yes...now that I think about it, there's some magnetics place over there that wouldn't stop calling me some years back. Calls, texts, emails...over and over. The pay was absolute shit, and I'm unable to be around high magnetics. I told them both, but they literally wouldn't stop calling until I told them why I couldn't be there, medically, and do they want me to get a lawyer so we can talk about their calling me in a more formal setting.
I suspect that they can't get people to work for them, but you need to pay something more than literally Sheetz wages. (That's not a knock on Sheetz, they pay decent enough for gas station work.)
... I don't see that magnetics place in Springfield anymore, unless I'm just not searching for the correct terms.
