The terms you mentioned: working conditions, co-worker relations, policies and rules, are classified by Herzberg's original theory as "Hygiene Factors".

Step 1: Understand Herzberg's Two-Factor Theory: This theory, proposed by psychologist Frederick Herzberg, suggests that there are certain factors in the workplace that cause job satisfaction (Motivators), while a separate set of factors cause dissatisfaction (Hygiene Factors).

Step 2: Define Hygiene Factors: According to Herzberg, hygiene factors are those job factors which are essential for existence of motivation at workplace. These do not lead to positive satisfaction for long-term. But if these factors are absent / if these factors are non-existant at workplace, then they lead to dissatisfaction.

Step 3: Identify the Hygiene Factors: In Herzberg's theory, hygiene factors include aspects like company policies, supervision, working conditions, salary, safety, and co-worker relations. These factors are considered extrinsic to the work itself and are related to the conditions under which one performs the job.

Step 4: Understand the role of Hygiene Factors: The absence of hygiene factors can create job dissatisfaction, but their presence does not motivate or create satisfaction. Instead, satisfaction comes from within the job itself (which are called Motivators, such as achievement, recognition, the work itself, responsibility, and advancement).

So, in summary, working conditions, co-worker relations, policies and rules are classified as Hygiene Factors in Herzberg's original theory. They are necessary to ensure an employee does not become dissatisfied, but they do not necessarily lead to satisfaction.
