in class work with sources

I would say the source number two is helpful to use as one of the source, about the topic of emotional labor. It is simple not complacated. The article talks about the result or the impact of service job can do to a person. It causes stress and the feeling of being idiot. The first source it is hard because it contains so much information. the third source I think I could use it but not like as much as source number 2
