At Discover Card we pull credit simply to check if they have debt with discover card. Other than that they do not care. My CFI who now fly’s for the industry had a Ch 7 bk before he got hired. A credit check may be used to build character in their eyes. But you cannot judge character based from their credit. You could be the most honest, reliable, trustworthy, person in the world and something could happen, your wife may get cancer, and you got into debt paying for your medical expenses. You got divorced, and had to battle debt in civil courts. Bad things do happen to good people. If they see your constantly bouncing checks, or that you never pay your bills it may tell something about you, it may not. Your financial situation is none of their business, it is discrimination not to hire you because you overloaded on debt when you were young, and hit rock bottom.
If employers did not hire people with bad credit our unemployment rate would be through the roof. In Utah, 2005 1/30 people filed for chapter 7 bankruptcy. Utah has had the highest bankruptcy percentages in the nation. IIRC. So if employees refused jobs because of bad credit, 1/30 people in Utah could be unemployed.
