Apparently, an entirely arbitrary process. I have witnessed staff members hired, fired, rehired, and fired again. Often, seemingly random individuals are hired in as foremen with outlandish outcomes. Foremen have been terminated for theft, drug use, achohol, and misuse of company vehicles and fuel. Obviously these behaviors were sustained by better financial times but now seem starkly out of sync with today's requirements for success or even survival. The "Hiring and Interview Process" is, at best, still in developmental stages.
