The median hourly wage of quality control inspectors was $15.88 in May 2010. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $9.68, and the top 10 percent earned more than $26.72.
Although most quality control inspectors work full time during regular business hours, some inspectors work evenings or weekends. The most desirable shifts are generally given to workers who have seniority. Overtime may be required to meet production deadlines.
