Final answer:
Taylorism, developed by Frederick Winslow Taylor, created an adversarial relationship between labour and management by emphasizing productivity over worker well-being and reducing the workforce to repetitive, standardized tasks.
Step-by-step explanation:
The system which created an adversarial relationship between labour and management by overlooking the workforce is known as Taylorism, a system of management named after Frederick Winslow Taylor. This management approach emphasized maximizing productivity by dividing manufacturing tasks into short, repetitive segments without much concern for worker well-being, leading to a dehumanized workforce. Taylorism focused on improving factory efficiency by standardizing work processes and limiting workers to repetitive tasks, reducing human contact and diminishing opportunities to collaborate or engage in skillful work.
