In Latin America people have fewer unions, usually centered around construction because it is very easy to die on a construction site. Latin American countries are among those least friendly to unions and there have been anti union crackdowns and proposed legislation to ban them or limit their functions. For example teacher unions. Parents are not defending teachers they are just being treated like disposable objects that are thrown away the moment they defend themselves, and they can do it because the unemployment rate is 10% and only 40% hold an employment contract.
