To combat absenteeism effectively, it is essential to start with precise measurement: breaking it down by center, team, time slot, and type (medical, justified, unjustified). Only then can truly focused actions be designed. The impact of workplace absenteeism goes far beyond direct costs, such as the salary for work not performed. Its consequences are profound: it creates an extra burden on the rest of the team, reduces productivity, affects service quality, and can severely erode the work environment. For this reason, its strategic management has become an unavoidable priority for any Human Resources department.
