The Nigerian military has meddled in the Nigerian politics in this fourth republic to the extent of past military heads of states becoming the country’s president in a democratic dispensation. This has influenced the military personnel’s commitment to the organization. Our study investigated political influence on military wimpy in organizational commitment: roles of team psychological safety and spirit at work. Two hundred and fifty (250) military personnel were drawn from Nigerian Army Cantonment in Ikeja, Lagos State using a purposeful sampling technique to select the participants. The participants consisted of 170 males and 80 females. Their ages ranged from 25-45, with a minimum age of 26 years. Three instruments (Psychological Safety, Organizational Commitment and Spirit at Work) were used in the study. Two hypotheses were tested and cross-sectional survey design was adopted, while correlation and multiple regression analysis were used for data analysis. The results indicated that team psychological safety had no significant influence on organizational commitment among Nigerian army personnel, while spirit at work was a significant positive predictor of organizational commitment among Nigerian army personnel (â = .13, t = 2.04, p = .002). Work place interventions that will help Nigerian military personnel’s improve team psychological safety and spirit at work by building organizational commitment and adapt to organizational changes were suggested. The paper makes original contribution to research in the area of organizational commitment by cracking into the busy schedule and closed-system of Nigerian military personnel and throw a more comprehensive and holistic understanding of organization commitment process in Nigerian military in integrating perspectives that focus on the internal group psychological context (team psychological safety) and intangible variable (spirit at work) of Nigerian military.
