This research investigated the cushion effect of perceived organizational welfare packages and effective leadership on counterproductive work behavior among telecommunication employees in Nigeria. Two hundred (200) participants for the study were selected using convenience sampling from two major telecommunication companies in Nigeria. The participants were one hundred and four males (104) and ninety-six (96) females. The perceived organizational welfare package rating scale, the BCE leadership style rating scale, and the counterproductive work behavior checklist (CWB-C) assisted in the data collection. The study made use of predictive research design and multiple regression analysis in testing the three hypotheses postulated. Hypothesis one stated that the perceived organizational welfare packages will significantly and negatively predict counterproductive work behavior. The result showed that perceived organizational welfare packages significantly and negatively predicted counterproductive behavior, Beta = - .35**, P< .01. Hypothesis two stated that effective leadership will significantly and negatively predict counterproductive behavior. The result agreed with the hypothesis, Beta = - .15**, P< .01. Hypothesis three stated that effective leadership will significantly moderate the relationship between perceived organizational welfare packages and counterproductive workplace behavior. The result also agrees with the third hypothesis, Beta = -.02**, P< .01. In line with the findings, it was recommended that organizational welfare packages and effective leadership are recipe for reducing counterproductive work behavior within the work place.
