Which of the following is NOT considered a hygiene need according to Herzberg?

According to Herzberg's Two-Factor Theory, hygiene needs refer to factors that can lead to job dissatisfaction if they are inadequate but do not necessarily motivate employees when they are sufficient. Hygiene factors typically include work conditions, salary and benefits, and relationships with supervisors.

Personal achievement, on the other hand, is categorized as a motivator. It falls under the factors that actually enhance job satisfaction and motivate individuals to perform at higher levels. Motivators are intrinsic to the work itself and include aspects like personal growth, recognition, and the sense of achievement that comes from one’s accomplishments. Hence, personal achievement is not considered a hygiene need, making it the correct answer in this context.
