Explanation:

Achievement, Recognition and Responsibility are Motivation Factors. Pay and security belongs to the category of Hygiene Factors. Both motivation and hygiene factors are part of Herzberg’s Two Factor Theory. 

Briefly, we asked our respondents to describe periods in their lives when they were exceedingly happy and unhappy with their jobs. Each respondent gave as many "sequences of events" as he could that met certain criteria— including a marked change in feeling, a beginning, and an end, and contained some substantive description other than feelings and interpretations... The proposed hypothesis appears verified. The factors on the right that led to satisfaction (achievement, intrinsic interest in the work, responsibility, and advancement) are mostly unipolar; that is, they contribute very little to job dissatisfaction. Conversely, the dis-satisfiers (company policy and administrative practices, supervision, interpersonal relationships, working conditions, and salary) contribute very little to job satisfaction.
