If the gov't comes and checks you for illegals and you cannot show where you have done 'due diligence' of checking SSN then you go to jail and lose the company!. Gov't sells company at great price to employees (1st choice) or others and bingo! no more illegals on the payroll.
you know it always cracks me up how some employers say it cost so much to do back ground checks on thier employees..
They are full of shit. I can get a basic crimal background check, credit check, SS # varry for less then $30, Its about $50 with a drug test. Normally you hear back in 3-5 biz days. The back ground check I do( life scan, the CA DOJ check/ finger printing, lets you work in schools) Is only $75, gives them instant bonding, Add in a drug, TB, and credit check for about $120. Hell there is a online service that lets you check SSN and its free.
Trust me the employers know what they are hiring... they just don't care, they want the cheap labor.
