Word-of-mouth leads in Charlotte - any advice?

A friend who works at a local manufacturer says there are openings not advertised online. I worked as a warehouse supervisor before this. One is a print shop, one is an accounting firm and one is a clinic. Does anyone have similar leads?

Small employers often hire on recommendation. Ask neighbours, former co-workers and your library.

Visiting in person worked for a trades job. For office jobs, email was better.
