Differentiate between states covered under state plans and states covered under federal osha jurisdiction

State plans must be at least as effective as federal OSHA, but some states, such as California, have chosen to adopt stricter standards. In four of these locations (Connecticut, Illinois, New Jersey, New York, and the Virgin Islands), the state plan covers public-sector workers only; private-sector employers are still covered by federal OSHA.
