Employers shouldn't be required to do background checks. While it is often done for professional positions it is an extra cost. A small franchise (say a family owned set of Arby's stores) shouldn't have to do anything beyond the basic SS number and see that it matches. If ID/SS don't match than sure put some onus on the company but 'legal teams' pssh not every job is going to do that kind of screening. What type of jobs do you think illegals are getting?
