Hygiene -the environmental factors (noise, heat, salary, status, relationships,) they are related to working conditions and must have a basic level. If the conditions are below this minimum level, the work suffers, but productivity is not influenced upward if working conditions are above the basic level. These conditions must be met in order not to generate dissatisfaction.
The meaningful factors - motivation - (career development, responsibility, autonomy, ...) These factors correspond to meaningful higher Maslow. They are intrinsic to the work and responsibility of the individual development. Once hygiene factors provided motivation factors can be filled to generate satisfaction.
