Scholars in this field have found through painstaking research that there are several factors influencing employees' enthusiasm for work. One of the key factors is that employees' enthusiasm for work is not only related to their salary to a certain extent, but also closely related to whether their salary (namely, the distribution problem) is in line with their efforts. During the working process, employees will sum up several methods to measure their own salary level, so as to gain a sense of fairness. First is the horizontal comparison, that is, compared with the input-output ratio obtained by other employees at the same level or position in the organization; The second is the longitudinal comparison, that is, to compare the input-output ratio obtained by oneself in the past; The second is the longitudinal comparison, that is, to compare the input-output ratio obtained by oneself in the past. To measure the fairness of one's own salary level through these two comparisons, if one thinks that he/she has been treated fairly, he/she will have a high degree of satisfaction. On the contrary, the unequal sharing of the cake will cause great resistance to the subsequent services.
