From the study it was found out that in the organization the employees are highly aware of the absenteeism problem that currently happen in the public sector where mean (M)=4.10 with standard deviation, SD=0.61 . All the three variable is analyse through multiple regression whereas the results shows that leadership is significant (Beta value=.352, p=.000), while training & career development and teamwork have no significant value (Beta value=.147, p=0.58) and (Beta value=.008, p=.923). Thus, it indicates that leadership is the most influential driver of employee engagement with the awareness of absenteeism. However, gender as moderator variable has no effect on the relationship between independent and dependent variables as all the P-value after R2 change is p>0.05. In conclusion, since leadership do influence the awareness of absenteeism in RMCD, few action need to be taken by the organization by relating the element of leadership in engage employees to reduce the absenteeism in public sector.
