Grocery stores are open more hours and days than most work establishments, so workers are needed for early morning, late night, weekend, and holiday work. With employees working 30 hours a week, on average, these jobs are particularly attractive to workers who have family or school responsibilities or another job.

Most grocery store workers wear some sort of clothing, such as a jacket or apron, that identifies them as store employees and keeps their personal clothing clean. Health and safety regulations require some workers, such as those who work in the delicatessen or meat department, to wear head coverings, safety glasses, or gloves.

In 2002, cases of work-related injury and illness averaged 7.3 per 100 full-time workers in grocery stores, compared with 5.3 per 100 full-time workers in the entire private sector. Some injuries occur while workers transport or stock goods. Persons in food processing occupations, such as butchers and meatcutters, as well as cashiers working with computer scanners or traditional cash registers, may be vulnerable to cumulative trauma and other repetitive motion injuries.
