Clayton Alderfer’s ERG Theory is often seen as a

Solution

The frustration-regression principle is the primary unique feature of Clayton Alderfer’s ERG Theory that distinguishes it from Maslow’s Hierarchy of Needs.   Maslow’s theory is strictly a satisfaction-progression model which means that an individual only moves up the hierarchy as lower-level needs are satisfied. On the other hand, Alderfer’s model suggests that if a person is continually frustrated in their attempts to satisfy a higher-level need like Growth, they may regress and redouble their efforts to satisfy a more concrete, lower-level need like Relatedness. For example, an employee denied promotion (growth frustration) might focus more on socializing with coworkers (relatedness) or just ensuring job security (existence).   Note - The ERG theory does not claim existence needs are non-motivational. In fact, it views Existence needs (similar to Maslow’s physiological and safety needs) as highly motivational. The ERG model does not ignore self-actualization; it incorporates it into the Growth category.
