This study considers how employees' tenacity might enhance their propensity to engage in knowledge exchange with organizational peers, as well as how the positive tenacity-knowledge exchange relationship is invigorated by two types of role conflict: within-work and between work and family. Using data from a large Mexican organization in the logistics sector, this study shows that tenacity increases knowledge exchange, and this effect is stronger at higher levels of within-work and work-family role conflict. The invigorating role of within-work role conflict is particularly salient when work-family role conflict is high. These findings inform organizations that the application of personal energy to knowledge-enhancing activities is particularly useful when employees encounter severe workplace adversity because of conflicting role demands.
