According to the article "One More Time: How Do You Motivate Employees?", what is the central concept behind Frederick Herzberg's motivation$-$hygiene theory?

$$ Job satisfaction and job dissatisfaction are independent of each other and are influenced by different factors.

Employees are only motivated by monetary incentives and job security.

Extrinsic factors, such as recognition and achievement, have a greater impact on motivation than intrinsic factors.

Job satisfaction and job dissatisfaction are directly correlated, meaning that improving one will automatically improve the other.
