The increasing deficit of workers in the U.S. has resulted in employers hiring a greater number of workers of which many are teens and students. Most of these young workers are unskilled, seek temporary and parttime work, and are willing to work for low wages. They work after school hours, weekends, holidays, and during summer. Many vocational/technical school students work during school hours in co-op, school-to-work, or tech-prep programs. The 2003 NIOSH Alert publication (1) indicated that 70-80% of teens have worked for pay during their high school years outside of home (2) and also faced workplace hazards. The U.S. Bureau of Labor Statistics (3) reported in 2000 that 2,9 million students (age 15-17) worked during the school year, and 4,0 million students (age 15-17) worked during the summer. U.S. students work at service jobs such as cashiers, gas stations attendants, cosmetology assistants, photography, entertainment/recreation, and health services; in restaurants; retail, grocery stores; manufacturing; agriculture, and in construction.
