They are certainly not lazy. All of the Spanish people I knew worked well at their jobs, but they also knew how to kick back and relax with good food and music and wine.
The only issue I ever had with Spain was trying to get a meal at my personal dinnertime (6PM). Many restaurants don’t even open until 7.
They eat LATE. Which is not good if you have a body clock that goes off at 6AM. :-)
