In the early 1900s, many states passed legislation designed to "protect" women workers. In California, for example, a 1916 law prohibits women from employment in jobs that involve lifting "any excessive burden," cleaning moving machinery, work on moving abrasives, work in core making rooms, manufacture of nitro compounds, handling of any dry substance with specified amount of lead, employment in work environments that are not sufficiently lighted, ventilated, or sanitary, messenger service, bell boy, trucking, gas/electric meter reader, taxi cab driver, elevator operator, guard on streets or subways, work in pool hall/bowling alley, delivery service, or "employing women under any conditions detrimental to their health or welfare." How would these protective laws affect the employment and wages of women and men workers?
