How did John D Rockefeller treat his workers in the industry?

John D. Rockefeller's treatment of workers in the oil industry was often characterized by a focus on efficiency and profit, which sometimes led to harsh working conditions. While he implemented some measures for safety and welfare, such as medical care for workers, his companies were also known for long hours, low wages, and a lack of job security. Strikes and labor unrest were common as workers sought better conditions, reflecting the tension between Rockefeller's business practices and the needs of his employees. Overall, his approach balanced a paternalistic attitude with a relentless pursuit of cost-cutting and profit maximization.
