The purpose of this project work was to assess the link between project managersâ€™ leadershiprnattributes and organizational citizenship behavior (OCB) of construction projects in Adama townrnvia the lens of project staff members. To examine the issue under consideration the study wasrnguided by quantitative approach. Specifically, an exploratory descriptive survey research designrnwas employed. Two construction project sites (ASTU and RVU) functioning at Adama cityrnadministration were randomly selected. Census survey was utilized to include 38 project staffrnmembers. To measure the leadership attributes the Leader Attributes Inventory/Observer-RatingrnForm was employed; whereas, to assess OCB the adapted version of OCB-scale were utilized. Therndata were analyzed with descriptive statistics (mean scores, correlation, and ranking methods)rnand finally examined using pertinent literature. The study ascertained: (1) the extent to whichrnproject managers leadership attributes are related to OCB; and (2) the dominant leadershiprnattributes exhibited by project managers as perceived by project staff members. The study foundrnthat there is a significant positive linear relationship between projects managersâ€™ leadershiprnattributes with OCB. Besides, the study identified the top and the least exhibited project managersrnleadership attributes. In conclusion, the results of this study uncovered the moderate amount ofrnlinkages between leadership attributes and OCB. In light of the findings a great deal is expectedrnof construction project managers to promote employees OCB. Hence, developing projectrnmanagersâ€™ leadership attributes revealing drive, trust, tolerance, interpersonal and organizationalrnskills could count for employees OCB. In addition, since the nature and behavior of project leadersrnvary across different contexts, so that may affect construction project employees OCB differently,rnfurther study needs to be undertaken in a larger scale.rnKeywords:
