Do you know how much where they being paid? In my experience, this only happens when the wages are very low. I don't know the direction of causality: do higher wages motivate workers not to be more professional, or do low wages result in the 'good' workers avoiding those jobs? Even in the US, a lot of minimum-wage McJobs have relatively high levels of absenteeism
