Well I'll tell ya, I was self employed and if I didn't work I didn't get paid. First rule of thumb for me was, never let the competition in ( as well as know the comp.).
When it got to busy for me to handle, I tried hiring through newpaper, word of mouth, placement & employment agencies, etc. I didn't have a lot of people to chose from so I picked the most qualified. Bottom line I tried my best to train but let them all go. Let it be know that my best employee was my wife, although she couldn't take the pressure or work load (construction industry). I put in as many hours as need to get the job done. It took such a toll on me and my family but at least now I'm retired.
