Our goal was to analyze the positive effect of job crafting activities involving nursing home employees on their perceived quality of care, and the moderating effect of organizational identification. A two-wave non-experimental design (with an interval of 12 months) was used. The Job Crafting Questionnaire, the Identification-Commitment Inventory, and the Quality of Care Questionnaire (QoC) were administered to 226 nursing home employees in two waves. The results of the hierarchical regression analyses found significant association between job crafting subdimensions and quality of care twelve months later. Organizational identification was shown to play a moderating role in these relationships when analyzing the effect of cognitive crafting. In this sense, the effect of cognitive crafting on quality of care is only found with high levels of identification. The findings highlight the importance of the job crafting dimensions (task, relational and cognitive) when it comes to enhancing quality of care in residential homes for the elderly. This is especially relevant for cognitive crafting among employees with high levels of organizational identification. This research provides managers with guidance when allocating job crafting opportunities aimed at making improvements in quality of care. In this respect, organizations must offer job crafting training to stimulate and support their employees and, on the other hand, managers should encourage employees to craft their jobs, gearing their needs, abilities, and goals to corporate values and competencies.
