In 1833 the Government passed a Factory Act to improve conditions for children working in factories. Young children were working very
long hours in workplaces where conditions were often terrible.
The basic act was as follows:
•No child workers under 9 years of age •Employers must have a medical or age certificate for child workers •Children between the ages of 9-13 to work no more than 9 hours a day •Children between 13-18 to work no more than 12 hours a day •Children are not to work at night •Two hours schooling each day for children •Four factory inspectors appointed to enforce the law throughout the whole of the country.
