"Not only has the education industry been the site of rapid employment growth, it has also been the site of growing labor unrest worldwide in the second half of the twentieth century. According to the VVLG data, the education industry is one of the few industries that has experienced a rising trend of labor unrest in the final decades of the twentieth century. Moreover, the geographical spread of teacher labor unrest has been far greater than was the case historically for the textile and automobile industries."
