Many employers are now doing credit score checks for applicants before hiring them. Not hiring someone because they have a low credit score is branding this person as someone who is dishonest and may steal from your company. People have a poor credit score because the monthly payments for loans, medical bills, etc. are more than what they can afford because of higher utility bills and low pay. Finance charges and late fees push the amount even higher making the monthly payments untouchable.
Every credit check lowers your credit score. Stop companies from denying employment due to credit. Definitely use criminal checks for financial positions.
