What trend occurred in workplace injuries and illnesses after OSHA was established?

The establishment of OSHA led to a significant decrease in workplace injuries and illnesses. This reduction can be attributed to the implementation of comprehensive safety regulations and standards that OSHA introduced to promote safe working conditions across various industries. The agency's focus on creating awareness, providing training resources, and enforcing safety compliance effectively encouraged employers to adopt safer practices and reduce hazards in the workplace.

Additionally, OSHA's efforts, such as conducting inspections, promoting worker rights to report unsafe conditions, and offering educational programs, also contributed to a heightened safety culture. This shift not only improved outcomes for workers but also enhanced overall productivity and morale, showcasing the positive impact of OSHA's intervention in workplace safety.

Other options suggest either no change or an increase in injuries and illnesses, which do not align with the documented data showing a decline in such incidents following OSHA's implementation. The notion that the decrease only applied to large employers also fails to consider the widespread influence of OSHA regulations across all employment sectors, benefiting workers regardless of company size.
