American workers are more ___ than their european counterparts.

Productive

Explanation:

It has been suggested that American workers are more productive than their European counterparts. However, there are many factors that come into play in this comparison. For example, the definition of "productivity" is not the same across different cultures. Moreover, European workers work at different times during the day, usually beginning and ending later than their American counterparts. Finally, even if productivity is lower in Europe, European workers might focus on different activities that, while not important for their American counterparts and thus not considered to be "productive," can be very important for them.
