Nike was founded in 1964 and employs over 33,000 people worldwide. In the 1990s, it was revealed that some of Nike's subcontracted factories had poor working conditions including low pay, long hours, and even child labor. This damaged Nike's reputation. Since then, Nike has implemented a code of conduct for suppliers and created programs to improve factory conditions and monitor compliance, though progress has been slow and critics argue it is mainly for public relations purposes rather than true social responsibility.
