Ray Crosby, the principal owner and president of Champion Safe Co., says he was never "an expert" on the paperwork required to show a worker is legally allowed to work in the United States. He is now. On Tuesday, U.S. District Judge Paul Cassell fined the Provo company $80,000 for harboring undocumented immigrants and placed it on three years' probation, giving immigration officials the right to inspect paperwork on workers' employment eligibility without prior notice. "There's a lot of burden placed on small employers today," Crosby said, but added the safe-manufacturing business will abide by the law. Employers are required to check documentation, such as birth certificates and work permits, to confirm new hires can work in the United States. Prosecutors say that despite being notified by the government in 2000 that about 15 of its employees were working with incorrect or fraudulent Social Security numbers, Champion Safe continued to employ undocumented workers. Authorities raided the business in February 2003 and detained 107 employees in its 150-person work force. No workers were prosecuted, but many were deported. Crosby pleaded guilty on behalf of the company last fall to harboring undocumented workers. - Pamela Manson
