No, I don't think all people in Spain work the same number of hours. Also, I think "other European countries" are not a homogenous group, average number of hours worked differs per country.

Well people in Spain have a lot less working hours than in other European countries such as Greece, Poland, and Malta. Whether work hours means doing actual work or just loafing around is harder to measure.
