The study investigated the role of organisational justice, age and gender on organisational commitment and job involvement among casual workers from two oil servicing companies in Omoku, Rivers State, Nigeria. The convenience sampling technique was used to select 399 participants made up of 251 males and 148 females. Participants’ ages ranged between 24-52 years (M = 37.94, SD = 7.35). The design adopted was cross-sectional survey design while the One-Way Multivariate Analysis of Variance was utilized to analyze data collected. The findings showed that casual workers who reported the presence of organisational justice had higher levels of commitment and were more involved in their jobs. However, age and gender showed no significant influences on organisational commitment and job involvement among casual workers. The study reaffirmed the need for managers in organisations to infuse policies geared towards enhancing organisational justice in their work places as this could improve work commitment and job involvement.
