This essay sheds light on what are "the need theories of motivation", explicates why "Alderfer's ERG theory of motivation" is the most rational need theory of motivation, demystifies the benefits of attaining your needs that are apart of "Maslow’s hierarchy of needs theory", and reveals the challenges of attaining your needs that are apart of "Maslow’s hierarchy of needs theory" in this essay. There are a myriad of "need theories of motivation. The need theories of motivation" delineate why people are motivated to partake in goal-related behaviors. There are exogenous factors and endogenous factors that have bearing on motivating people to partake in goal-related behaviors. Because people have unmet needs that need to be assuaged, they will make extreme concessions to attempt to meet their needs. A person for instance who chooses to work a real private sector employee job based on voluntary demand is often inapt to ever assuage all of his basic needs even if he earmarks over 104,000 hours over the course of his lifetime into working a real private sector employee job based on voluntary demand to appease a real private sector employer. Much to the dismay of people who work real private sector employee jobs based on voluntary demand, most real private sector employee jobs based on voluntary demand are deemed to be dead end, highly time consuming, debilitating, minimum wage, dispiriting, unfulfilling, undesirable, harrowing, distressful, brutally wretched, ineffably agonizing jobs that not only drain almost all of your sacrosanct time and that do not pay anything close to 1/4 of a subsistence wage for affording housing, but are jobs that also induce chronic stress, chronic fatigue, chronic burnout, an undermined well-being, and poor health. Most of the real private sector employee jobs based on voluntary demand dispossess employees of almost all of their waken hours, provide them with minimal compensation at a minimum wage, and do not provide them with any income generating assets, benefits, nor pension. Lamentably, most real private sector employers do not care furnish their employees with anywhere close to a subsistence wage since they are on keen on minimizing their labor costs at all costs. Almost all of the profits that companies generate are reserved for its executives and shareholders. It is less cumbersome for companies to offer massive compensation to their executives when they are able to minimize their labor costs. It is also less arduous for the companies to be able to offer sizeable retainer fees to their external directors when they are able to are able to minimize their labor costs. People often grossly underestimate how lucrative it can be to a Chief Executive Officer of a highly profitable company. The pay grade that the board of directors set forth for the Chief Executive Officer’s compensation is enormously lofty. An exorbitant amount of Chief Executive Officer earn over $165,000,000 in compensation. If a Chief Executive Officer for instance earned $165,000,000 per year in compensation then he would be receiving about $22.035 per second which is also $79,326.92 per hour. In the event that a company paid an assistant manager $10 per hour which is $20,800 per year and paid a Chief Executive Officer $165,000,000 per year in compensation then it would denote that the board of directors the CEO’s time to be worth 793,169% more than their company’s assistant managers based on their pay grades which they believe are commensurate with their productively levels. If companies paid a livable wage to their employees then the Chief Executive Officer who earns about $22.035 per second, $165,000,000 per year may possible need to take a pay cut to render it possible for the employees to receive a livable wage. The CEO earns about 793,169% more per hour than an assistant manager who for instance earns an hourly gross rate of $10 per hour at the company. The average CEO is often unwilling to take even a modicum of a pay cut if it was the only way to offer the employees a livable wage. The needs of a real private sector employer and employee are often diametrically opposed to one another. The real private sector employer often voraciously yearns to provide the real private sector employee with the absolute minimum amount of emolument for the maximum amount of time worked.
