ABSTRACT This study investigated the effect of family responsibility on work commitment of professional women workers. Two hundred (200) women employees engaged in the financial institutions were used as participants. One hundred and twenty (120) were unmarried while eighty (80) were married. Among the married ones, thirtyeight (38) had children while forty-two (42) had no child. The participants were selected using stratified random sampling method. The instrument that was used is the Organizational Commitment Questionnaire (OCQ) developed by (Mowday, Porter and Steers, 1979). The Chi Sq statistics was used for data analysis. Three hypotheses were postulated and they are H0:1) – increase in family roles would not significantly affect work commitment of women, (H0:2) – age of the youngest child would not significantly affect a mother’s commitment to work and (H):3) – the number of children a woman has would not significantly affect her work commitment. Result of the X2 analysis indicated that none of the hypotheses was significant (P>0.05). The findings and their implications were discussed and the limitations of the study were stated and suggestions made for further research.
