Interesting and high quality report on global rights index. An example of high quality and global secondary data source. It offers a list of countries rating from 1 to 5+ (pp. 15), where 5+ means “No guarantee of rights due to the breakdown of the rule of law” and 1 “Irregular Violations of Rights”.
I also like the mixed methods approach applied, as well as the sophisticate development of indicators to measure the violation of working rights (pp. 29-35). You can also see in the first pages examples of the worst countries, and a a but consistent evaluation of working rights violation in many other countries of Asia, America, Africa and Europe.
