Securing a high level of dedication among workers of an organization has been a challenging issue in modern-day organizations. Most employees are actually employed by originations but they are not fairly committed to the discharge of their responsibility, which is to aid the attainment of organizational objectives. This study investigated the effect of organizational justice on the level of commitment obtained from employees of the organization. The objectives of the study were to determine if distributive justice affects commitment of academic staff in Kaduna State University; to determine if Procedural justice affects commitment of academic staff in Kaduna State University; to examine the extent to which Interpersonal justice affects commitment of academic staff in Kaduna State University; and to examine how Informational justice affects commitment of academic staff in Kaduna State University. Data was obtained through the usage of a questionnaire using a sample of 267 from a total population of 964. Data was regressed, and the result revealed that distributive justice, Procedural justice, Interpersonal justice and Informational justice all affect commitment of academic staff in Kaduna State University. It was recommended that there is a need for organisations to make justice and fairness a critical component of their organisational culture so that managers do not treat their subordinates unjustly. Organisations are to ensure that there are consequences to all who engage in acts of injustice. There should also be an internal control mechanism that would not just reduce injustice but would aid in preventing such acts.
