In many companies, HR and finance departments look at people from two perspectives: HR looks for causes and patterns (why people leave, where absenteeism is growing, what is happening with engagement), while payroll keeps an eye on costs (how much it really costs and how it affects the bottom line). Power BI allows you to combine these worlds into a single, consistent data model and turn scattered HR and payroll reports into decision-making dashboards. This is particularly important because turnover is rarely “just an HR problem” – the cost of replacing an employee is estimated at between 50% and 200% of their annual salary, depending on their role and seniority. In turn, sick leave in Poland is on a scale that cannot be ignored: in 2024, 27.4 million medical certificates were registered, totaling 290 million days of absence. When we compare this data with the cost of man-hours, overtime, and replacements, we get a picture that is ideal for weekly or monthly management – not “after the fact” at the end of the quarter.
