Section 8 of the Asylum and Immigration Act 1996 is the primary measure for combating illegal working. It provides employers with a statutory defence from conviction if they check and record certain specified documents belonging to potential employees. To support employers in meeting their responsibilities under section 8, IND produced short (summary) guidance which was distributed widely among other Government Departments and agencies. If further guidance on this legislation is required, the booklet refers the reader to the immigration and nationality directorate website where comprehensive guidance is available, and there is also a reference to the Employers’ Helpline which offers a dedicated service for employers by advising on the legislation on preventing illegal migrant working. The Employers’ Helpline also disseminates hard copies of the comprehensive guidance on request. The comprehensive guidance makes clear that this legislation covers contracted and sub-contracted employment.
