Given the analyses, which reveal that growth in temporary employment now far exceeds the level explainable by recent workforce entry rates of groups said to prefer temporary jobs, firms should be discouraged from creating excessive numbers of temporary positions.

 

OG11-12

Many United States companies have, unfortunately, made the search for legal protection from import competition into a major line of work.

大致的句意是能理解的，但是highlight的地方还是不太明白，请NN们指教，最好能帮偶翻译出来~

谢谢~~
