The correct answer is A. Working conditions
Step-by-step explanation:
Frederick Herzberg's two-factor theory claims that one of the two main factors causing dissatisfaction in employees is hygiene factors. These factors are related to general working conditions, payments, and benefits, status, among others that depend mainly on the employer and the policies of the company. Moreover, hygiene factors differ from motivators (the second factor in the theory) because motivators are related to recognition, promotion, and similar that depend on the employers but also the performance of employees.
According to this, the factor that would be considered a hygiene factor is "working conditions" because this factor includes elements such as an old or inadequate building that depend mainly on the employer, which is a characteristic of hygiene factors. Also, other factors such as promotion, training or recognition are part of motivators rather than hygiene.
