Nearly a third of Americans work on the weekend.
The U.S. has the highest incidence of people reporting any paid weekend work. 29 percent of Americans reported performing such work in the American Time Use Survey, more than three times the rate among Spanish workers.

It’s important to note that this doesn’t necessarily mean that these workers are working 9 to 5 every weekend, only that they reported performing paid weekend work in a time use survey. This would include things like going into the office for a few hours to finish up a project.

More than a quarter of Americans work at night.
27 percent of American workers report working nights, which the study defines rather strictly as any work performed between 10 PM and 6 AM. If the definition of “night” were expanded earlier into the evening, say 7 PM, this number would be considerably higher.
