I am not saying otherwise, total working hours have increased, but if you divide by workers have decreased, https://elpais.com/economia/2023-05-03/las-horas-trabajadas-alcanzan-las-cotas-previas-a-la-gran-recesion-tras-dispararse-en-el-primer-trimestre.html .

But if there were manipulation of data the amount of hours wouldn’t increase. There is a difference in saying the data is manipulated and saying the data don’t tell you the whole story, one questions the data and good faith, the other questions the completeness of the analysis.

Furthermore, the unemployment rate doesn’t tell you the whole story because working hours and salaries. The later have not increased meaningfully in the last 20 years… meaning people actually need to work more to have the same life level.
