The nation’s eyes are focused on Chicago as 29,000 teachers and support staff remain on strike in a protest against substandard schools and reneged pay raises.

As the Chicago Teachers Union soldiers on, it’s important to remember the plight of teachers nationwide. The New York Time’s Catherine Rampell has put together a few charts showing that American teachers work longer for less pay than teachers in most other developed countries.

Rampell notes that the “average primary-school teacher in the United States earns about 67 percent of the salary of a average college-educated worker in the United States. The comparable figure is 82 percent across the overall O.E.C.D. [Organization for Economic Cooperation and Development].”

Here’s a chart showing the ratio of salary between middle school teachers compared to full-time, full-year college-educated workers. American teachers fair better than those in Estonia, but are worse off than the average of rich countries in the OECD:

Next, let’s take a look at teaching hours. As you can see, Chile and Argentina are the only countries where teachers work longer hours:

If Chicago’s teachers succeed, they may inspire other educators to follow suit. By the looks of these numbers, they certainly have something to protest over.
